WebMay 1, 2008 · Tresca–Mises model. In this model the yield and plastic potential functions are approximated as a cylinder, which has a circular cross-section in the deviatoric plane, so that the yield and plastic potential functions are expressed as (3) F = J 2 - R = 0, G = J 2 - K = 0 where R is a material constant representing the shear strength of the soil. Tresca was also among the designers of the prototype metre bar that served as the first standard of length for the metric system.
