夹层结构冲击动力学研究综述

A review of studying on impact dynamics of sandwich structures

为了解夹层结构在冲击载荷作用下的防护性能,通过回顾对夹层结构冲击动力学研究进展,分别从理论建模方法、变形失效、流固耦合效应、芯层结构形式及设计参数五方面对其进行分类论述;并对研究进行总结、对今后研究方向进行展望。

In order to understand the protection of sandwich structures against impact, studying on impact dynamics of sandwich structures at home and abroad was reviewed here. The review was expounded in five aspects, including modeling method, deformation failure, fluid-structure interaction （FSI） effect, cell topologies, and design parameters. At last, the conclusions were drawn, and the trend of future study was envisaged.
