Von Mises yield criterion

The von Mises yield criterion suggests that the yielding of materials begins when the second deviatoric stress invariant reaches a critical value. For this reason, it is sometimes called the -plasticity or flow theory. It is part of a plasticity theory that applies best to ductile materials, such as metals. Prior to yield, material response is assumed to be elastic.

In materials science and engineering the von Mises yield criterion can be also formulated in terms of the von Mises stress or equivalent tensile stress, , a scalar stress value that can be computed from the Cauchy stress tensor. In this case, a material is said to start yielding when its von Mises stress reaches a critical value known as the yield strength, . The von Mises stress is used to predict yielding of materials under any loading condition from results of simple uniaxial tensile tests. The von Mises stress satisfies the property that two stress states with equal distortion energy have equal von Mises stress.

Because the von Mises yield criterion is independent of the first stress invariant, , it is applicable for the analysis of plastic deformation for ductile materials such as metals, as the onset of yield for these materials does not depend on the hydrostatic component of the stress tensor.

Although formulated by Maxwell in 1865, it is generally attributed to Richard Edler von Mises (1913). Tytus Maksymilian Huber (1904), in a paper in Polish, anticipated to some extent this criterion. This criterion is also referred to as the Maxwell–Huber–Hencky–von Mises theory.

Sastramech: Yielding criteria for Ductile materials

The problem of deducing mathematical
relationships for predicting the conditions at which plastic yielding begins
when a material is subjected to a complex state of stress is an important
consideration in the field of plasticity. In uniaxial loading, plastic flow
begins at the yield stress, and it is to be expected that yielding under a
situation of combined stresses is related to some particular combination of the
principal stresses.

MECH-INFO: TRIAXIAL STRESSES AND YIELD CRITERIA( VON MISES CRITERION)

Consider a rod being subjected to tension in uni-axial tension test then it undergoes deformation when the stress applied exceeds elastic limit then it starts undergoing plastic deformation an at yield point the value of tension stress is equal to the yield stress an we can determine the stress at which plastic deformation starts
consider the same rod subjected to triaxial stresses that is it is subjected to stresses in the y-axis and also in the z-axis then a combination of stresses may lead to yielding or plastic deformation so when triaxial or bi-axial stresses are applied we never know at what stress yielding of the material starts
so the prediction of the stress value at which yielding occurs is given by yield criteria there are 2 basic criterions that are generally followed in calculating the yield stress there are
