考虑多种失效模式耦合的复合材料损伤分析
Damage Analysis of Composites by Coupling Multiple Failure Mode
摘要
Abstract
Composite damage failure form is various,the damage failure forms including laminated plate damage,colloid crack extension and interface debonding.To investigate damage of laminates,colloid crack propagation,interface delamination inherent relations among the three kinds of damage failure,the hybrid bending(MMB)fracture finite element model is firstly established by using ABAQUS/Explicit software,by comparing the simulation and experimental results,which proves the accuracy of MMB model.Then,the internal relationship among the three failure modes was studied by combining the Hashin failure criterion,extended finite Element method(XFEM)and cohesive force model(CZM).The results show that the damage of laminates can not only affect the time of interface viscous separation failure,but also affect the crack propagation path in colloid,which provides a certain reference for numerical analysis of the damage problem of composites.关键词
