Determination of the optimal fibers' orientation in A ply of a laminated plate is presented to attain a maximal strength criteria. The optimization method couples genetic algorithms approach with the finite element method. In-plane loaded plates and square plates subjected to bending are optimized in numerical examples.

Non-rigid components assembly simulation requires complex and difficult modelling tasks. This paper presents how ANATOLEFLEX solution can support user to take into account assembly sequence, joint with defaults, composite or metallic material properties, form default from manufacturing processes, and contact modelling in order to build a full and realistic assembly simulation. An implementation of this solution is presented on a representative aeronautical structural assembly use case with simulation results analysis. This use case illustration leads to conclusions on future industrial applications of realistic assembly simulations such as tolerance analysis or gap maps estimation for shimming processes.
