Abstract

A dynamic constitutive model of fiber-reinforced resin matrix composites considering temperature effect was proposed. It was used to predict the impact limit speed of composite laminates. High-speed bullet impact tests of fiber-reinforced resin matrix composite laminates were carried out at 25, 160, and 200°C, and the impact limit speed V_c was calculated using the test results. The test results showed that V_c of carbon-fiber-reinforced resin matrix composite laminates decreased with increasing ambient temperature. On this basis, a dynamic failure model of fiber-reinforced resin matrix composites was established considering the influence of ambient temperature. A VUMAT user subroutine was also developed to embed the failure model into the finite-element analysis software package. Then, the high-speed impacts of composite laminates at different temperatures were simulated numerically. The magnitude of V_c was predicted by the bisection method. A comparison of simulation results with test data showed that the error was smaller than 5%.

基于三维哈辛准则的不同环境温度下复合材料层压板冲击极限速度预测方法

提出了一种考虑温度效应的纤维增强树脂基复合材料动态结构模型。该模型用于预测复合材料层压板的冲击极限速度。在 25、160 和 200°C 下对纤维增强树脂基复合材料层压板进行了高速子弹冲击试验，并利用试验结果计算了冲击极限速度 Vc。试验结果表明，碳纤维增强树脂基复合材料层压板的 Vc 随环境温度的升高而降低。在此基础上，考虑到环境温度的影响，建立了纤维增强树脂基复合材料的动态失效模型。此外，还开发了一个 VUMAT 用户子程序，用于将失效模型嵌入到有限元分析软件包中。然后，对复合材料层压板在不同温度下的高速冲击进行了数值模拟。Vc 的大小是通过二分法预测的。模拟结果与测试数据的比较表明，误差小于 5%。
