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 ...

Writers have different ways of developing plans. I find the concept-sheet (Section 3, below) is a good way to do it. Figure 1. The Design Process. Designing a paper is like designing anything else: there are five essential steps. The Embodiment. The embodiment is the first draft. Get ...
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 ...
Some materials use grain-sized composites on a nanometer scale. These nanocomposite-based substances tend to have higher values for modulus of elasticity, how quickly the stress on the material changes when under pressure. The chemical arrangements of molecules on the nanoscale mean these materials ha...
