【摘要】 介绍了利用内接或外切多边形去取代原有的非线性超凸曲面进行硬塑薄壳承载能力计算的方法。该方法涉及构造多边形边界的选取、计算矩阵K1和K2的构造、薄壳承载能力计算等过程,阐述了计算过程中的关键问题,给出了具体的计算实例。更多还原

【Abstract】 Introduce the calculating methods of rigid plastic laminates’ carrying capacity,which apply internal access or excircle polygons to replace the intrinsic nonlinear superconvexity.That method is involved to the selection of formation polygons’ boundary,the formation of calculating matrix K1 and K2,the calculations of laminates’ carrying capacity,etc.Expatiating the key techniques in the calculations,giving the idiographic examples of calculation.更多还原
