TOPOLOGY OPTIMIZATION WITH STRESS AND FATIGUE CONSTRAINTS
Motivation: Reduce the post processing phase of design of mechanical components descending from a TO process by including stress and fatigue constraints within the optimization problem.
- Maximum stiffness design lead to high stress peaks in the vicinity of re-entrant corner ? bad design with respect to strength requirements
- Stress and fatigue remove peaks + more relevant designs
Challenges:
- High CPU requirement
- Singularity of the stresses
Extensions:
- Lattice structures
- 3D problems
