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 Combined Loading? The objective of combined loading analysis is to evaluate the stresses in a structural member when it’s exposed to more than one type of load at the same time. Basically, these are forces that act on a structure in different ways, and understanding how they interact is crucial for designing buildings,…
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…
Solidification refers to the process of a substance changing from a liquid to a solid state. In metals and alloys, this is a complex process that includes dendrite formation, compositional segregation, zone formation in the final casting structure, and the creation of microporosity due to shrinkage. What is Solidification This transformation is evident in various…
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…
Modern vehicles have become significantly heavier over the past several decades due to increasing safety requirements, consumer expectations, and advances in automotive technology. Modern safety regulations require automakers to reinforce Body-in-White (BIW) structures to improve crash energy management while also integrating and packaging additional safety technologies such as cameras, radar sensors, and advanced driver assistance…
How Temperature and Strain Rate Affect Impact Testing Results The graph below shows the effect of temperature on the mechanical properties of a carbon steel during impact testing. Most materials display similar temperature sensitivity for elastic modulus, yield strength, ultimate strength, and ductility. As temperature increases, tensile strength, elastic modulus, and yield strength of a…
What Is Automotive Steel? Automotive steel is the family of steel grades used to build cars, from low-carbon body panels to ultra-high-strength safety cage components. Steel is used in the frame, body structure, closures, chassis, and powertrain parts because it can be tuned to meet crash, stiffness, formability, cost, and durability requirements at the same…
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…
