| 摘 要： | 讨论了飞机风挡层合玻璃的抗弹穿叠层设计方法，建立了风挡层合玻璃三维有限元分析模型。对层合玻璃材料采用具有失效模型的弹塑性本构关系，用非线性Ｌａｇｒａｎｇｅ有限元程序模拟了飞机层合玻璃的子弹穿透动响应过程，给出了层合玻璃弹穿的计算实例，数值分析为防弹层合玻璃的设计提供了理论依据。

| Abstract: | The design method of anti bullet multi layer composite plastics is discussed. A three dimensional FE model of multi layer composite plastics is developed. The dynamic process of bullet perforating multi layer composite plastics is then simulated by a nonlinear FE codes. A constitutive model of elastic plastic with failure model is adapted in the analysis. The present numerical analysis provides a theoretical base for the design of anti bullet multi layer composite plastics. |
