High velocity impact response of quasi-isotropic carbon fiber reinforced polymeric laminates cured from unidirectional plies is studied using finite element models. Rigid steel spheres are used as projectiles. The intraply meso-model originally propo

This paper presents a new approach to generate and optimize parallel fiber trajectories on general non planar surfaces based on level-sets and the Fast Marching Method. Starting with a (possibly curved) reference fiber direction defined on a (possibl

In this paper, topology optimization is used to design aircraft pylons. Original results for two Airbus pylons are first presented. An innovative bi-level optimization scheme is then proposed, which combines topology and geometric optimizations. At t
