卷积型加权残值法求解薄壳的动力学问题

DYNAMIC PROBLEMS FOR THE THIN SHELL SOLVED BY METHOD OF CONVOLUTION-TYPE WEIGHTED RESIDUALS

摘要: 板壳等弹性体，受到动荷载作用时，其动力分析问题是比较重要且难于解决的.利用卷积型加权残值法，推导出Gurtin变分原理，并应用卷积型加权残值法计算了薄壳的动力学问题，为计算薄壳的结构动力学问题提供了一种有效的方法.

Abstract: Dynamic analysis of elastic body for plates and shells isimportant and difficult. The method of convolution-type weighted residuals is a new method for solving dynamic problems of thin shells.It is shown to be effective in this paper.
