摘要

复合材料的损伤失效形式是多样的

其损伤失效形式包括层合板损伤、胶体裂纹扩展和界面脱黏。为了探讨层合板损伤、胶体裂纹扩展、界面脱黏3种损伤失效之间的内在联系

先利用ABAQUS/Explicit软件建立混合型弯曲(MMB)断裂有限元模型

通过数值仿真结果与实验结果的比较

从而证明MMB模型的准确性。然后结合Hashin失效准则、扩展有限元法(XFEM)和内聚力模型(CZM)来研究3种失效模式的内在联系。结果表明: 层合板损伤不仅可以影响界面脱黏失效发生时间

同时也能影响胶体中裂纹扩展路径

为复合材料损伤问题数值分析提供了一定的参考。

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.
