    Machine design inevitably involves the use of structural steel members for items such as frames for tables, building structures, crane supports, etc. This process involves building a profiles that can consist of 2D and 3D curves that layout the path of the members to trace followed by end conditions for members that are connected or intersected. The Structural Steel process is a specialty application where the framework for this capability has been added for 2015. You can use these tools to build a single part consisting of many different members and sizes that can be trimmed to define the appropriate end conditions. In addition, these parts will automatically be called out in the Bill of Materials with the name and length of each member to give accurate cut lists for manufacturing.

Structural engineering is a specialized branch of civil engineering that entails analyzing and designing structures -- things like buildings, bridges and even concert stages. Engineering is a big discipline that involves a systematic approach to designing solutions to problems experienced in the real world. There are many different fields of engineering, like mechanical engineering, electrical engineering, civil engineering, chemical engineering and systems engineering. And within these categories there are various subcategories-- and structural engineering is a subcategory of civil engineering. Transcript Ever wonder how tall buildings can withstand windy days, or why bridges don't collapse when large trucks drive over them? The answer is structural engineering. Structural engineers use physics and math to design and analyze the sturdiness of structures, things like bridges, buildings, concert stages, and even roller coasters. Don't get me wrong. Designing any one of these things can involve multiple types of engineering, but it's structural engineering that's responsible for making sure that that structure won't collapse or fall over. You see, a structure must be able to handle the forces or loads that it's likely to experience. Take a skyscraper, for example. It not only has to support itself, but also all the people and furniture inside the building, and then external factors, like wind, snow, or an earthquake. The materials and geometry that make up a structure influence how it may respond to those forces. Different materials have different properties, like strength, weight, and flammability, that can influence a structure's sturdiness. For example, steel is generally stronger, and weighs more than wood, and different geometric shapes work better for different purposes. For example, a square or rectangular base can typically hold more weight than a triangular base. Structural engineers perform calculations to determine the best materials and shapes to use in order to build a study structure. The next time you find yourself at the top of a roller coaster, you can thank structural engineers for doing their part to make sure it's nice and sturdy.

Describes the results." NEW VERSION with improved video & sound: https://www.youtube.com/watch?v=xXOtdTa2ypU Public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Carbon_steel#Heat_treatment The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. Note that the electrical and thermal conductivity are slightly altered. As with most strengthening techniques for steel, Young's modulus is unaffected. Steel has a higher solid solubility for carbon in the austenite phase; therefore all heat treatments, except spheroidizing and process annealing, start by heating to an austenitic phase. The rate at which the steel is cooled through the eutectoid reaction affects the rate at which carbon diffuses out of austenite. Generally speaking, cooling swiftly will give a finer pearlite (until the martensite critical temperature is reached) and cooling slowly will give a coarser pearlite. Cooling a hypoeutectoid (less than 0.77 wt% C) steel results in a pearlitic structure with α-ferrite at the grain boundaries. If it is hypereutectoid (more than 0.77 wt% C) steel then the structure is full pearlite with small grains of cementite scattered throughout. The relative amounts of constituents are found using the lever rule. Here is a list of the types of heat treatments possible: - Spheroidizing: Spheroidite forms when carbon steel is heated to approximately 700 °C for over 30 hours. Spheroidite can form at lower temperatures but the time needed drastically increases, as this is a diffusion-controlled process. The result is a structure of rods or spheres of cementite within primary structure (ferrite or pearlite, depending on which side of the eutectoid you are on). The purpose is to soften higher carbon steels and allow more formability. This is the softest and most ductile form of steel. The image to the right shows where spheroidizing usually occurs. Full annealing: Carbon steel is heated to approximately 40 °C above Ac3 or Ac1 for 1 hour; this assures all the ferrite transforms into austenite (although cementite might still exist if the carbon content is greater than the eutectoid). The steel must then be cooled slowly, in the realm of 38°C (68.4°F) per hour. Usually it is just furnace cooled, where the furnace is turned off with the steel still inside. This results in a coarse pearlitic structure, which means the "bands" of pearlite are thick. Fully annealed steel is soft and ductile, with no internal stresses, which is often necessary for cost-effective forming. Only spheroidized steel is softer and more ductile... Normalizing: Carbon steel is heated to approximately 55 °C above Ac3 or Acm for 1 hour; this assures the steel completely transforms to austenite. The steel is then air-cooled, which is a cooling rate of approximately 38 °C (68 °F) per minute. This results in a fine pearlitic structure, and a more-uniform structure. Normalized steel has a higher strength than annealed steel; it has a relatively high strength and ductility. Quenching: Carbon steel with at least 0.4 wt% C is heated to normalizing temperatures and then rapidly cooled (quenched) in water, brine, or oil to the critical temperature. The critical temperature is dependent on the carbon content, but as a general rule is lower as the carbon content increases. This results in a martensitic structure; a form of steel that possesses a super-saturated carbon content in a deformed body-centered cubic (BCC) crystalline structure, properly termed body-centered tetragonal (BCT), with much internal stress. Thus quenched steel is extremely hard but brittle, usually too brittle for practical purposes. These internal stresses cause stress cracks on the surface. Quenched steel is approximately three to four (with more carbon) fold harder than normalized steel... Quench and tempering: This is the most common heat treatment encountered, because the final properties can be precisely determined by the temperature and time of the tempering. Tempering involves reheating quenched steel to a temperature below the eutectoid temperature then cooling. The elevated temperature allows very small amounts of spheroidite to form, which restores ductility, but reduces hardness. Actual temperatures and times are carefully chosen for each composition...

Title Structural Coloration of Metallic Surfaces Using Elliptical Vibration Texturing Speaker Prof. Ping Guo Assistant Professor Department of Mechanical and Automation Engineering, Chinese University of Hong Kong Time and Location June 1, 2017 4:10 PM Bainer Hall Room 1062 Abstract Micro-structured surfaces are assuming an ever-increasing role since they define the ultimate performance of many industrial components and products. Surface micro-structures, when carefully designed, can alter the optical, biological, tribological, and thermal properties of the original surfaces. The bottleneck of applying this new technology to commercial products is manufacturing efficiency. This talk demonstrates one example of using a novel vibration-assisted machining method for fast creation of periodic micro/nano-gratings for structural coloration. When the tool vibration is coupled with a constant cutting velocity, periodic cusps can be generated due to the machining marks. The periodic vibration-induced ripples can be precisely controlled in terms of spacing by changing the nominal cutting velocity. These periodic ripples, whose wavelength is in the visible spectrum, can introduce iridescent colors. The device design, theoretical analysis, experimental results, and potential applications of the process will be covered in this talk to demonstrate structural coloration of metals by direct machining. Biography Dr. GUO Ping received his B.S. degree in Automotive Engineering from Tsinghua University in 2009. He received his Ph.D. degree in Mechanical Engineering under the advisory of Dr. Kornel F. Ehmann from Northwestern University in 2014. He then joined the Department of Mechanical and Automation Engineering at the Chinese University of Hong Kong as an assistant professor starting in August, 2014. His research interests center on the paradigm of micro-manufacturing, including surface texturing, process micro-mechanics, miniature machine tools, micro-additive manufacturing, etc. License This talk is released under the terms of the Creative Commons Attribution 4.0 License.

Machine design inevitably involves the use of structural steel members for items such as frames for tables, building structures, crane supports, etc. This process involves building a profiles that can consist of 2D and 3D curves that layout the path of the members to trace followed by end conditions for members that are connected or intersected. The Structural Steel process is a specialty application where the framework for this capability has been added for 2015. You can use these tools to build a single part consisting of many different members and sizes that can be trimmed to define the appropriate end conditions. In addition, these parts will automatically be called out in the Bill of Materials with the name and length of each member to give accurate cut lists for manufacturing.

The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing and quenching. It is noteworthy that while the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding... Metallic materials consist of a microstructure of small crystals called "grains" or crystallites. The nature of the grains (i.e. grain size and composition) is one of the most effective factors that can determine the overall mechanical behavior of the metal. Heat treatment provides an efficient way to manipulate the properties of the metal by controlling the rate of diffusion and the rate of cooling within the microstructure. Heat treating is often used to alter the mechanical properties of a metallic alloy, manipulating properties such as the hardness, strength, toughness, ductility, and elasticity. There are two mechanisms that may change an alloy's properties during heat treatment: the formation of martensite causes the crystals to deform intrinsically, and the diffusion mechanism causes changes in the homogeneity of the alloy. The crystal structure consists of atoms that are grouped in a very specific arrangement, called a lattice. In most elements, this order will rearrange itself, depending on conditions like temperature and pressure. This rearrangement, called allotropy or polymorphism, may occur several times, at many different temperatures for a particular metal. In alloys, this rearrangement may cause an element that will not normally dissolve into the base metal to suddenly become soluble, while a reversal of the allotropy will make the elements either partially or completely insoluble. When in the soluble state, the process of diffusion causes the atoms of the dissolved element to spread out, attempting to form a homogenous distribution within the crystals of the base metal. If the alloy is cooled to an insoluble state, the atoms of the dissolved constituents (solutes) may migrate out of the solution. This type of diffusion, called precipitation, leads to nucleation, where the migrating atoms group together at the grain-boundaries. This forms a microstructure generally consisting of two or more distinct phases. Steel that has been cooled slowly, for instance, forms a laminated structure composed of alternating layers of ferrite and cementite, becoming soft pearlite. Unlike iron-based alloys, most heat treatable alloys do not experience a ferrite transformation. In these alloys, the nucleation at the grain-boundaries often reinforces the structure of the crystal matrix. These metals harden by precipitation. Typically a slow process, depending on temperature, this is often referred to as "age hardening". Many metals and non-metals exhibit a martensite transformation when cooled quickly(with external media like oil,polymer,water etc.). When a metal is cooled very quickly, the insoluble atoms may not be able to migrate out of the solution in time. This is called a "diffusionless transformation." When the crystal matrix changes to its low temperature arrangement, the atoms of the solute become trapped within the lattice. The trapped atoms prevent the crystal matrix from completely changing into its low temperature allotrope, creating shearing stresses within the lattice. When some alloys are cooled quickly, such as steel, the martensite transformation hardens the metal, while in others, like aluminum, the alloy becomes softer... https://en.wikipedia.org/wiki/Aluminium

One of the members of a new generation of stylish camping trailers that includes the Mogo Freedom and Happier Camper HC1, the Nest caravan is designed for a more luxurious road-tripping experience. It combines a sleek, infusion-molded monocoque body with a comfortable, fully featured interior. The Nest rides on 16-in wheels The Nest includes a washroom in the far driver-side corner On one side is a cooktop and counter/dining table The Nest sleeps two on a queen bed We've seen some impressive new camping trailers out of Oregon this season, including High Camp Trailers and Freespirit. The Nest adds yet another. Based in Bend, Nest Caravans completed its first prototype in late March and is now ready to start taking orders. We're very accustomed to seeing camping trailers built as boxes secured to metal frames. This traditional construction is exemplified quite well by the Teal Tail Feather since you actually start with a utility trailer and then assemble the camper body up from there. Nest eschews convention and integrates the frame and body into a single monocoque shell. The start-up says that the move cuts out 75 percent of the weight of the frame – there is still a small section of powder-coated steel tube frame at the front of the trailer secured to the monocoque via mechanical fasteners. It also assures that the infusion molding process provides the structural strength necessary for a functional home away from home.
