Geometrical Formulation of Yield Surfaces
Yield functions are commonly visualized as surfaces in the principal stress space, centered around the hydrostatic axis. According to the von Mises yield criterion, the yield surface takes the shape of a cylinder. However, it is not always immediately clear how the mathematical form of this criterion results in a cylindrical surface. In this post, the geometrical formulation of the von Mises yield criterion will be derived step by step. Read More ›
