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
