| 摘 要： | 本文首次采用直接配点法求解扁壳几何非线性平衡问题。计算实例表明，该法较过去惯用的最小二乘配点法具有计算量小，切线刚阵性态好等重大优点，所得的计算成果未见有文献报导。

| Abstract: | In this paper,direct collocation methods are first used to solve the problem of nonlinear equilibrium of shallow shells.The computational practice shows thatthis method has less CPU time,rapider convergence and better beliavior of tangentialstiffness matrix than the least square collocation methods,The numerical results obtained in present paper have not been reported in previous papers. |
