摘要
本文利用ANSYS程序,在弹塑性、大挠度范围内,建立考虑板件间相关屈曲作用的双坡楔形偏压柱的有限元模型,并模拟实际情况,在模型中引入初始几何缺陷和残余应力,研究几何参数及残余应力对其稳定承载力的影响。
The FEM model of two-way tapered eccentrically loaded column which consider the interactive buckling is built for the large-deflection and elastic-plastic analysis. In order to simulate the practical situation, the initial geometric imperfection and the residual stresses are brought in the model. The influence of the geometric parameters and residual stress to the in-plane stability carrying capacity is researched.
