【摘要】 本文将结构的初始几何缺陷视为初始位移,导出了具有初始缺陷的几何非线性问题的两种刚度方程,可用于一般的有初始缺陷的非线性弹性问题求解及其稳定性分析,也可用于分析结构局部缺陷对其整体特性及反应的影响.文末给出了算例.更多还原

【Abstract】 Two kinds of stiffness matrix equations of nonlinear problems with initial imperfections are presented while the initial geometrical imperfections are considered as initial displacements.The equations are useful for the solution of nonlinear elastic problems and buckling analysis with imperfections,and can also be used to analyzed effect of local imperfections on the whole characteristics and response of structures.更多还原
