Abstract

This study presents fully coupled ordinary state based peridynamic (PD) model for of laminated composites. The formulation includes coupling of both thermal and mechanical fields. In order to verify the proposed model, numerical simulations for benchmark problems are carried out and their results are compared with the ones from ANSYS solutions. First, the thermomechanical behaviour of the laminated composites subjected to both uniform and linear temperature changes are tested for single and multilayer composites. Then, fully coupled thermo-mechanical formulations are validated for laminated composites subjected to pressure shock. Finally, the crack propagation paths and temperature distributions are predicted for shock loading conditions. In conclusion, the present PD model is well suited for solving fully coupled thermomechanical problems for laminated composites including crack initiations and propagations.
