Hey guys, have you ever wondered how the mechanical properties of engineering materials are tested? From determining the strength and durability of materials to evaluating their elasticity, there are a lot of different methods used to test the mechanical properties of materials. In this article, we’re going to talk about some of the most common…
What is a combined loading? The objective of combined loading is to evaluate the stresses of a structural member when exposed to a variety of loads. Basically, these are forces that act on a structure in different ways, and understanding how they interact is crucial for creating buildings, bridges, automotive chassis and internal combustion engines….
What is carbon fiber made from? Carbon fiber is a composite material that is made of long strings of molecules attached together by carbon atoms and resin. The majority of carbon fibers produced are derived from polyacrylonitrile (PAN). The other 10% is composed of rayon or petroleum pitch. As a result, carbon fiber is a high-performance…
Solidification of metal is a complex process where molten metals and alloys turn into solid forms. It includes dendrite formation, compositional segregation, zone formation in the final casting structure, and the creation of microporosity due to shrinkage. What is Solidification Solidification refers to the process of a substance changing from a liquid to a solid…
Metalworking is the art of shaping metals into various tools, equipment parts, and structures. It involves forming, cutting, and joining metal pieces using techniques like welding, casting, and molding. In the industrial age, metalworking has developed into a sophisticated science. The industrial revolution has led to exponential growth in the scale of modern metalworking processes,…
What are common engineering materials and why are they important? Throughout history, the significant accomplishments of each era have consistently revolved around the development of new materials, playing a pivotal role in the advancement, prosperity, safety, and overall well-being of humanity. Since the dawn of civilization, it has consistently been the introduction of innovative materials…
Have you ever wondered why are cars so heavy? it seems like each year that goes by cars seem to get bigger and heavier! The average weight of a recently purchased vehicle in the United States reached a 4,329 pounds in 2022. This figure exceeds the 1980 average by over 1,000 pounds and reflects an…
What is the relation between temperature and strain rate? The graph below shows the effect of temperature on mechanical properties of a carbon steel. Most materials display similar temperature sensitivity for elastic modulus, yield strength, ultimate strength, and ductility. As temperature increase tensile strength, elastic modulus and yield strength of a material tends to decrease….
What is meant by dual-phase steel? Developed in the 1970s, dual-phase steel (DP) is a high-strength steel that provides theadvantages of high-strength steel without losing good overall elongation. As a result of itsmicrostructure consisting of both ferritic–martensitic microstructure. DP steel has good fatigue resistance making it ideal for automotive-related sheet-forming operations. Mechanical properties of common…
Objective The object of the experiment is to determine the material of an unknown specimen based on the material young’s modulus(E). Young’s modulus is the ratio of the stress to strain in the plastic region of the stress-strain diagram. This mechanical property is material specific. The data which was gathered during this experiment is as…
