04.2 - Structural Analysis and Design, Structural Dynamics, AeroelasticityAN XFEM FRAMEWORK FOR ONSET AND CRACK PROPAGATION FOR COMPOSITES BASED ON ACTION PLANE THEORYM.V. Angeloš, M.L. Ribeiroš, V. Titaš; šUniversity of Sao Paulo, Brazil A new framework for analysing crack onset and propagation through XFEM on tapered composite structures is presented. The model is based on the Action Plane Theory following the works of Puck. A parametric sensitivity analysis is provided in order to check model sensibility to parameters variation. Numerical examples are presented and compared to experimental data for validation. |
