A Boundary Value Problem in Nonlinear Elasticity II — The Inverse Method — Lesson 2

We start with a general expression of Cauchy’s stress and make observations regarding this expression. The kinematics of simple shear, hydrostatic stress, and the Poynting effect are explained. We show that normal stresses are needed to sustain the simple shear.

Answers to Frequently Asked Questions

In this video we will answer the following question:

  • We generally associate hydrostatic stresses with volume changes, however, there are no such volume changes here when the hydrostatic stress is non-zero. Why is that?
