Principal Stress — Lesson 3

Описание к видео Principal Stress — Lesson 3

This video lesson demonstrates that we can always change the coordinate system of an infinitesimal cube of material is such a way that the shear stress components are equal to zero; the three normal stresses left in the tensor are the principal stresses. Mathematically, we calculate the eigenvalues of the 3 x 3 tensor matrix to find the principal stresses. This lesson is part of the Ansys Innovation Course: Stress and Local Equilibrium.
