摘要

本文总结了IMT项目HICAS“复合材料飞机结构的高速冲击”,该项目涉及开发一种设计方法和有限元模拟工具,用于预测复合材料飞机结构的高速冲击响应。取得的成就包括测量三种飞机复合材料系统的高速率力学性能,开发新的复合材料在高速率载荷下的失效模型,将模型应用于商业有限元代码中,并通过在测试结构中模拟冲击来验证代码。

Simulation methodology for high velocity impact in composite aircraft structures

The paper summarises the IMT Project HICAS on ‘High Velocity Impact of Composite Aircraft Structures’ which was concerned with developing a design methodology and FE simulation tools for predicting the high velocity impact response of composite aircraft structures. Achievements include measurement of high rate mechanical properties of three aircraft composite systems, development of new failure models for composites under high rate loads, implementation of models into commercial FE codes and code validation by simulation of impact in test structures.
