WebThe von Mises equation is a measure of the “shear” strain in the material and does not account for the hydrostatic straining component. For example, strain values of ε x = ε y = ε z = 0.001 yield an equivalent strain ε eq = 0.0. WebThe derivation of this form of the von Mises stress is based on the principal axes and arrives at the final result that is , of course, expressed in terms of the principal stresses …

A quantity called the equivalent stress or von Mises stress is commonly used in solid mechanics. The equivalent stress is defined as 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.
