摘要

摘要: 本文在文[1]的基础上,给出了用于层合板的静力分析和动力分析(固有频率)的变分原理,并据此给出了相应的有限元公式。大量算例表明这一方法给出令人满意的数值结果。

Abstract: In a previous paper (1)we proposed a new displacement model of laminated composite plates This model strictly satisfies the continuity conditions of displacement and strass betwccn the layers, and the numbar of unknowns is independent on number of layers.In this paper the finite element method based upon this model is proposed, and numbers of numerical examples are given.
