For each scenario and iteration, a Failure Criterion failure criterion is calculated, which represents the goal of the optimisation and based on which the design is generatedbased.
A Failure Criterion value of 1 is always the objective of the optimisation. Four different types of Failure Criteria are available (von Mises Stress, FFF Thumb Rule, Directional Dependent Tsai-Hill or Tsai-Wu). More information regarding the Failure Criteria here.
The Safety Factor calculates the goal for the optimisation in regard to the material properties (material limits) for the chosen Failure Criterion. As a second option, a stress goal can directly be defined. This should be a value, that is fitting to the material and LBCs. The following two examples show how the goal for the optimisation is calculated:
