Design of Lightweight Composite Structures: A Parameter Free Structural Optimization Approach

摘要

This contribution presents computational concepts and algorithmic techniques for simulation and gradient-based optimization of geometrically nonlinear and large-scale finite element models of composite structures. Focus is put on efficient adjoint sensitivity analysis to deal with very large design spaces. Parallelization is applied to all computation phases: simulation, sensitivity analysis, as well as optimization. Several examples illustrate the methods, show the applicability to large problems, and prove the high parallel efficiency.
