摘要

本文提出了一种将模态展开法与含缺陷有限区域的有限元表示相结合的方法来分析复合材料层合板的瞬态响应。为说明这一点，本文详细研究了含正表面断裂裂纹的层合板的模型问题。数值结果显示了裂纹深度对瞬态响应的影响。

Modal representation of transient dynamics of laminated plates

A technique combining the modal expansion with the finite element representation of a finite region containing defects is presented here to analyse the transient response of a laminated composite plate. As an illustration, a model problem of a laminated plate containing a normal surface breaking crack is studied in detail. Numerical results are presented showing the effect of the crack depth on the transient response.
