What is fatigue stress in engineering? So, what exactly is fatigue stress? Basically, it’s when a component or structure starts to weaken and break down over time due to cyclical stress or loading. Even if the stresses put on the component are within acceptable limits, fatigue failure can still occur due to the frequency of…
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 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….
