Abstract (EN): An optimisation model for structural reliability maximization of composite structures under dynamic loading conditions is proposed. The failure probability is obtained using a procedure based on level 2 reliability analyses adapted for dynamic response. The material properties of the ply are the random normal variables. The optimisation process is based on a Hierarchical Genetic Algorithm where a master population evolves with a net of slave sub-populations. The proposed topology aims to link the Most Probable failure Point search with the maximisation of structural reliability. The design variables are the ply angles of the composite laminates.
