摘要
在Przemieniecki和Gupta等人的研究基础上,建立了动态有限元的一种新形式——二维动态四边形单元,推导出其动态形函数矩阵、刚度和质量矩阵。本文结果可供实际分析应用。
The finite dynamic element method(DEM) is quite efficient in improving the accuracy of the dynamic analysis of structures. In order to expand the application field of the DEM, based on the studies by Przemieniecki and Gupta et al, a two-dimensional quadrangular finite dynamic element is established in this paper, and its dynamic shape functions, stiffness and mass matrices developed herein can be used in practical analyses.
