Abstract : Shell-type structures were and are being analysed using the Finite Element Method with 2D shell-type elements. However, for laminates a full 3D solution is required since the complexity of the material behaviour law. The Proper Generalized Decomposition can obtain 3D solutions while keeping the 2D complexity of 2D shell approaches. However, the PGD fails when dealing with complex geometries. We propose a technique, based on the Domain Decomposition technique, that is able to generate complex geometries from easier ones. Numerical examples show the performance of the method.
