Abstract:
We consider a numerical method for
constrained nonlinear programming, that is widely used in mechanical engineering
and that is known under the name SCP for sequential convex programming. The
algorithm consists of solving a sequence of convex and separable subproblems,
where an augmented Lagrangian merit function is used for guaranteeing
convergence. Originally, SCP methods were developed in structural mechanical
optimization, and are particularly applied to solve topology optimization
problems. A new challenge for SCP methods is the solution of free material
optimization (FMO) problems which contain additional semidefinite variables and
even nonlinear semi-definite matrix constraints. A few formulations are
investigated in more details and possible solution approaches are outlined.
