Second invariant j2
WebThe three principal stresses, as well as most other stress invariants, can be rewrit-ten in terms of three core invariants: the first invariant of the stress tensor, I 1, and the second … The maximum distortion criterion (also von Mises yield criterion ) states that yielding of a ductile material begins when the second invariant of deviatoric stress reaches a critical value. It is a part of plasticity theory that mostly applies to ductile materials, such as some metals. Prior to yield, material response can be assumed to be of a nonlinear elastic, viscoelastic, or linear elastic behavior.
