Minimizing the Material Volume with Stress Constraint

Within this section an example is presented where the material volume is minimized under a stress constraint.

The described example uses the following model:

(Design elements are shown in blue, the elements in red are defined as non-design elements due to loads and boundary conditions.)



The optimization setup is to minimize material volume having a constraint on the‘Maximum von Mises stress’.



The following diagram shows the difference between the maximal elemental centroidal Von Mises stress from solver and from SIMULIA Tosca Structure:
