摘要
为了较好地解决大规模的工程问题 ,提高分析效率 ,本文根据近几年发展起来的相对位移板壳单元及层合结构的有限单元法 ,利用“补空”或“夹空”处理 ,构造了一种新的层合梁单元。由此 ,可以减少单元数目数 ,大幅度提高计算效率。数值算例表明 ,此法简单有效 ,并能达到相当满意的精度 。
To analyze engineering problems of large scale easily and effectively, the Method of Virtual Laminated Element (MOVLE) is presented herein according to the plate shell element of relative displacement and finite element method(FEM) of sandwich structure. Furthermore, a new laminated beam element are put forward in this paper. By this method, the number of needed elements can be greatly decreased. The example results show that this algorithm is simple and effective to obtain satisfying design requirments.
