摘要
本文采用加权残数法分析了考虑几何非线性和初始缺陷的圆柱壳在轴压作用下的弹塑性稳定问题.文中对理想弹塑性材料柱壳推导出了增量形式的基本方程,并用伽辽金配点法求解了该基本方程。最后给出了圆柱壳在轴压作用下的数值计算结果.
The weighted residual method is used to analyse the elastoplastic buckling of cylindrical shells with geometric nonlinearity and initial imperfection under the action of axial compression.The incremental basic equations for shells made from perfect elastoplastic material are derived,and are solved by Galcrkin-collocation method.Finally the results of numerical calculations are presented.
