Poisson’s ratio, Strain energy & Thermal Stress – expressions

Today we will briefly discuss a couple of very important terms and concepts from the elasticity chapter. Those are Poisson’s ratio, Strain energy, Thermal Stress, etc. We will also derive expressions for these. This post is the 3rd post of the Elasticity series. Already in our last 2 posts, we have discussed the meaning of […]

Hooke’s Law – stress and strain – Modulus of Elasticity

In our last post, we have discussed Elasticity and Plasticity. Here we will continue with that discussion and gradually cover Hooke’s Law and Modulus of Elasticity. On the way, we will learn two more terms: stress and strain. Finally, we will cover (a) Young’s Modulus (2) Shear Modulus (3) Bulk modulus. So let’s start. Stress  To understand Hooke’s […]
