Tresca Yield Criterion¶ The Tresca yield criterion is another example of a common criterion used for determining the maximum stress of a material before yielding. Calculating yielding with Trescas method always results in a lower result compared to the von Mises method. Von Mises Yield Criterion (J2 Flow Theory) The von Mises yield criterion states that a material will yield when the von Mises stress at any point reaches a maximum (critical) positive value termed .Given , then according to the von Mises yield criterion, the material will yield when:. where is a positive constant that is dependent on the type of material. convergence or non-convergence is related to the yield criterion. This paper presents an analysis and comparison of several yield criterions in common use and deduced the substitutive relationship between Slope Safety Factor Analysis Using ANSYS Maximum Shear Stress Criterion: The maximum shear stress criterion, also known as Tresca's or Guest's criterion, is often used to predict the yielding of ductile materials. Yield in ductile materials is usually caused by the slippage of crystal planes along the maximum shear stress surface.

Weisgerber ‡ Show more In my opinion the von-mises rule could be used in spite of tresca as a failure criterion is used through out the code. However, use of tresca criterion might lead to numerical difficulties in plastic analysis (unfortunately I couldn't find any quote from the web..) and that's why it's not supported by ansys or abaqus. Of course, for each category of materials one has to decide on the most applicable failure criterion (Surely VM is not always suitable!). If a material in general follows VM yield criterion, and it hardens as well, then specifying the kinematic hardening rule will in fact take care of different yield limits during tensile/compressive cycl
