摘要 首先通过实验研究了轴压含有凹陷圆柱壳的稳定承载能力;其次,从考虑圆柱壳的凹陷塑性成形过程以及不考虑凹陷成形过程(仅把凹陷当作结构的不规则变化)两个方面,利用Ansys软件对含有凹陷圆柱壳的稳定承载能力进行数值分析;最后,对比两种分析所得出的结果,得到了凹陷塑性效应对圆柱壳稳定承载能力的影响。 Firstly, experimental studies on the stability and carrying capacity of cylindrical shells with dent under axial compression are carried out. Secondly, the plane model of cylindrical shell is built by ansys to analyze the stability and carrying capacity of cylindrical shell under two kinds of situation of considering the process of plastic figuration of dent and not. Finally, comparing two kinds of results, conclusion that the influence of plastic effect of dent on stability and load carrying capacity of cylindrical shell is gained.
