The Failure Criterion can be chosen in the studies tab for every optimisation scenario. Dependet Dependent on the intention of the optimsation optimisation it can be chosen between the equivalent von Mises Stress, a FFF Thumb Rule or directional dependent Tsai-Hill or Tsai-Wu Failure Criteria. More information reagarding regarding the Failure Criteria here.

E.g. for isotropic material behavior behaviour the Failure Criterion can be the von Mises stress. The Failure Criterion is the von Mises Stress distribution normalized to the value which corresponds with the chosen Stress Goal. The Stress Goal is calculated with the tension strength of the material and the safety factor. Values above one exceed the optimisation target, values beneath show areas with more optimisation potential. The maximum value can be displayed in a chart over the number of iterations.
