【摘要】 本文描述一种迭代解法,用“等弧长法”沿解的途径取步长,然后应用牛顿(?)莱弗莱或修正的牛顿(?)莱弗逊法于每一个步长进行平衡迭代。它可以同任一种自动步长增量法相结合用以追踪超极限响应并且在应用于考虑几何与材料效应板的非线性分析中得到了良好的结果。更多还原

【Abstract】 The present paper describes mainly an iteration strategy which uses the“constant-arc-length”method to step along the solution path and then applies the Newton-Raphson (N.R)or modified Newton-Raphson(m.N.R)equilibrium iteration at each step.It can be used in conjunction with any of the automatic step length increment procedures to trace the post limit response,and has got good results in being applied to the problems of nonlinear analysis of plates considering geometric and material effects[1] .更多还原
