摘要/Abstract

摘要： 在ABAQUS/Explicit中建立复合材料层合板三次冲击的三维仿真模型,采用预制分层损伤的方法,将前一次冲击损伤的状态变量预制进下一次冲击模型中,并将三维Hashin准则和刚度退化方案编入VUMAT子程序中。对层合板三次冲击过程中的层内损伤、层间损伤和接触力进行分析。结果表明,仿真结果与冲击试验结果吻合良好,所建立的模型可以较好地反映复合材料层合板三次冲击下的损伤演化过程。和后续冲击相比,第一次冲击的最大接触力最小,分层损伤的形状主要由第一次损伤形成,后续冲击仅增加分层损伤的损伤面积。

Abstract: In ABAQUS/Explicit, a three-dimensional simulation model of three impacts of composite laminates is established. The state variables of the previous impact damage are prefabricated into the next impact model by means of prefabricated layered damage method, and the three-dimensional Hashin criterion and stiffness degradation scheme are programmed into the VUMAT subroutine. The intra-layer damage, inter-layer damage and contact force of laminates during three impact process were analyzed. The results show that the simulation results are in good agreement with the impact test results, and the established model can better react to the damage evolution process under the three impacts of the composite laminate. Compared with the subsequent impact, the maximum contact force of the first impact is the smallest, the shape of the delamination damage is mainly formed by the first damage, and the subsequent impact only increases the damage area of the delamination damage.
