摘要
本文应用梯度法求解文献[1]提出的锥柱结合壳转折区塑性极限分析的非线性问题,得到了更准确的数值结果。同时表明了文献[1]的近似处理比较合理,可以简化工程计算。本文的计算机程序对求解更为方便。
The nonlinear problem of plastic limit analysis for near intersection region of cone-cylinder jointed shells under external uniform pressure is exactly solved by means of gradient method (descent method) and the results obtained are more accurate than those presented earlier by the author under the assumption of the equality of axial length of plastic flow region for shells of both the cene and the cylinder.
