-
摘要: 本文用最小二乘配点法分析开孔球形扁壳在环形载荷或均市载荷作用下的非线性轴对称屈曲问题。计算表明:本方法收敛稳定,结果准确,解法简捷、统一,易于推广更复杂的问题。Abstract: This paper suggests the use of the least square collocation method to analyse the nonlinear problem of axisymmetric static buckling for a shollow spherical shell containing a circular hole under uniformly distributed pressure and ring loading around hole. As some conerete examples showed that the method presented possesses these advantages, such as stability in convergence and accuracy in results. Funthermore, the method appears to be readily exteaded to more complex problems.
