Minimizing the Material Volume with Stress Constraint

This section presents an example 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 nondesign elements because of 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 the solver and from SIMULIA Tosca Structure:
