Recent progress in the optimal design of composite structures: industrial solution procedures on case studies

In this paper, recent developments carried out in the SAMCEF finite element code and in the BOSS quattro optimization toolbox are presented. Those developments aim at simulating high non linear effects in laminated composite structures (post-buckling, collapse, delamination) and at optimising the composites with respect to those structural responses. The use of Sequential Convex Programming and of Surrogate-Based Optimization methods is discussed on industrial optimization problems
