Stress-based Failure Criteria University of British Columbia

The Tresca yield criterion is piecewise linear, while the von Mises yield criterion is non-linear. However, the Tresca yield surface can involve singularities. The differences in predictions between the two conditions are considerably small.

For the states of uniaxial or equibiaxial stress, the two criteria are equivalent. At other stress states yielding occurs at lower stress values according to the Tresca conditions; under equal loading conditions, the Tresca criterion predicts larger plastic deformation than the von Mises.

Summary of Von Mises Failure Criterion

Yield Criteria for Ductile Materials and Fracture Mechanics of Brittle Materials Brittle materials are materials that display Hookean behavior (linear relationship between stress and strain) and which fail at a discrete strain. Plastic materials display a variety of yielding behaviors associated with changes in the internal structure of the material at a fixed level of strain and at a fixed

Stress-based Failure Criteria

Von Mises Yield Criteria Von Mises postulated (1913) that a material will yield when the distortional energy at the point in question reaches a critical value. The distortional energy written in terms of the 2D principal stresses and the yield stress is as follows.

Lecture 31 Von Mises Yield Criteria - YouTube

From Tresca, if we calculate the Maximum Shear Stress, t max, developed in a uniaxial tension test at yielding (s x =S Y; s y =0), we would find that t max = s x /2 = S Y /2 and predict the Shear Yield Stress, t Y = S Y /2 = 17, or SY:tY=2.

Mises yield criterion, which depends solely on the value of the scalar von Mises stress, i.e., one degree of freedom, this comparison is straightforward: A larger von Mises value implies that the material is closer to the yield point.
