摘　　要：基于二维Hashin失效准则,在充分考虑低速冲击下层合板纤维和基体拉压失效等损伤模式下,计及材料退化并引入损伤因子,运用ABAQUS软件建立复合材料层合板低速冲击有限元模型。运用该模型深入研究层合板低速冲击问题,考察其动态响应和损伤演化过程,数值结果和实验值吻合良好,验证模型的合理性和准确性。在此基础上,通过对层合板进行各冲击工况的数值模拟,详细讨论冲击能量、铺层形式等参数对层合板低速冲击动态响应和损伤特性的影响规律。A finite element model for analyzing low velocity impact damage of composite laminates was established base on ABAQUS software platform, the typical failure modes, such as fiber break, matrix cracking were simulated by employing the two-dimensional Hashin criterion, material degradation and damage factor were taking into account in this model. By adopting this model, the dynamic response and damage propagation of laminates were studied. The numerical results well agree with the experimental results and thus verify the accuracy of the model. On this foundation, laminates under various impact conditions were simulated. Parametric studies were conducted to study the effects of the impact energy and stacking sequence on the dynamic response and the damage of composite laminates under low velocity impact.
