To determine the modulus of elasticity of steel, for example, first identify the region of elastic deformation in the stress-strain curve, which you now see applies to strains less than about 1 percent, or ε = 0.01. The corresponding stress at that point is σ = 250 N/mm...
To really help this concept stick, take a look at the following calculations that find the elasticity modulus of different materials: 1. Steel In this example, we’ll look at a steel rod and find Young’s modulus for it. Consider the equation if the following factors are true: The rod ...

to the original state is called the “elastic region” and the region above it is called the “plastic region.” In the elastic region, there is a linear relationship between stress and strain, which is known as “Young’s modulus” or the “modulus of longitudinal elasticity” and is ...

A stress-strain diagram is plotted during the tensile testing of a material to determine the relationship between the stress and the strain at different loads. Various properties of the material are calculated by using stress-strain diagrams such as modulus of elasticity, modulus of resilience, fr...
