Principal stresses are defined as the maximum and minimum normal stresses in a plane. Principal stresses are perpendicular to each other and oriented such that shear stresses are zero. For 3D stress ...

I was never very good at math, nor was I especially interested in it. I would avoid math homework for as long as I could, and when I finally got to it, I would suffer through it. Therefore, I’m ...

The fields of finite-element analysis, failure analysis, and solid mechanics all express stresses in terms of tensors. Engineering literature usually treats a tensor as a symbol dressed with indices ...
