Strain energy

Calculating the Energy stored in a deformed material

Here, we will see how the Load-extension graph of a body can help us to calculate the energy stored in a deformed material. We will take two Load-extension graphs for this. Energy stored in a deformed material that obeys Hooke’s law The first load-extension graph (figure 1a) belongs to a body that obeys Hooke’s law, […]

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 […]
