stress solve yeild criteria

[mark smith]

Hi Elmer team
I am doing some stress analysis and using the ResultOutputSolve to output results, I can write out Vonmises and Tresca stresses and wondered if there were any other yeild criteria available i.e. Mohr-Coulomb?
I can find no documntation which referes to either Vonmises or Tresca ?
