Casting constraints in structural optimization via a level-set method

Résumé

A novel strategy for handling the molding constraint for cast parts is presented. In a first step, a simple projection method for the velocity field is applied. If the optimized shape violates thickness constraints, this projection method is no longer sufficient and a general molding constraint is applied at the same time with thickness control. We apply an augmented Lagrangian method to impose the constraints and compute a shape derivative for the objective function. We show examples in 3-d.
