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.

Frequently Asked Questions on Von Mises Stress Explained

The purpose of this ongoing blog series is to make the Finite Element Analysis software within SolidWorks, more accessible to a wider audience of not-necessarily-engineering users. Who/What is Von Mises stress, and why do we use it in FEA analysis? I find distressing pleas for clarity out on the Interwebs discussion forums. Usually coupled with pages of blind-leading-the-blind responses, with maybe one or two calm, well-couched replies buried so deeply in the thread, one wonders how many actually probed deep enough to benefit. Then we have the danger of Wikipedia Engineering. I quote verbatim: “The Von Mises yield criterion[1] suggests that the yielding of materials begins when the second deviatoric stress invariant J_2 reaches a critical value.”Oh. My. God bless you, Wikipedia. Sometimes you are written by humans. But sometimes you are written by mathematics doctoral candidates who care not for the utility of the sentence, as long as there are many beautiful words.
