What Is Fatigue Analysis? Fatigue Stress, S-N Curves & Design Basics
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…

Combined Loading Explained: Axial Load, Bending & Normal Stress Formulas
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,…

Impact Testing: How Temperature Affects Energy Absorption and Hardness
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…

How are leaf springs designed?
A leaf spring is a basic type of spring often used for suspension in vehicles. Originally known as a laminated or carriage spring, and sometimes called a semi-elliptical spring, elliptical spring, or cart spring, leaf springs are one of the oldest forms of vehicle suspension. A Leaf spring consists of one or more narrow, curved,…

Determining Material based on Mechanical Properties
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…

Why understanding beam bending is important?
What is the importance of beams? The primary function of beams, regardless of the application, is to act as structural elements that transfer loads. In the civil engineering field, beams refer to horizontal elements which symmetrical sections, such as an i-beam. For example, in a building, beams support the weight of a building’s floors above, ceilings,…
