【摘要】 本文对含参数λ的非线性方程组f(α,λ)=O提出了在位移-载荷空间R~n+1中以弧长为参数追踪解曲线c(s)的弧长增量法,并统一地处理了搜寻极值点(extre-mum point)与分叉点(bifurcation point)的问题,我们将此法成功地用于弹性旋转薄壳的非线性分析。更多还原

【Abstract】 An approach for tracing solution curve c(s) of the nonlinear equation system f(α,λ)=0, using arc-increment method in the load-configuration space RR+1, is developed in this paper. Then the extreme points and the bifurcation points at the curve c(s) can be searched.The approach is successfully used to solve the nonlinear analysis of elastic thin shells of revolution.更多还原
