摘　　要：本文以“含裂纹零维度单元”模型研究裂纹对矩形板动态特性定量的影响,完成一种既能满足工程结构有关设计需要,又比较简单可行的计算模型.In this paper, the effect of cracks on the dynamic characteristics of plates is calculated by means of a model of zero dimension element with crack. (i. e. , The element length of the model on perpendicular direction of the crack is zero). The calculation model is simple and effective and can meet the needs of designing of engineering structures.
