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

Article Preview

Abstract:

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. Several industrial application examples illustrate the methods, show the applicability to large problems, and prove the high parallel efficiency.
