摘要
本文从扁球壳的积分方程组出发,通过新定义的残差表达式,用权余法详细地研究了扁球壳轴对称非线性弯曲和稳定问题.通过数值计算可以看出,本方法应用方便,精确可靠.
By deriving the integral equations of shallow spherical shell and then defining a new weighted residuals expression, the problems of a axisymmetric nonlinear bending and buckling in shallow spherical shells are studied by weighted residual method (WRM).
The numerical results show that the WRM is convenient for use and accuracy.
