| 摘 要： | 本文研究对称线布载荷作用下圆底扁球壳的轴对称非线性弯曲和稳定性,讨论了当几何参数固定而载荷位置发生变化吋壳体的屈曲行为,以及当载荷作用位置固定而几何参数发生变化时壳体的屈曲行为,分析了屈曲模式对临界载荷的影响,并就ν=0.3的情形给出了数值结果。

| Abstract: | This paper deals with the axisymmetric nonlinear bending and stability of spherical caps under axisymmetric ring load. The buckling behavior is studied for a cap with fixed geometry when the location of the ring load is allowed to vary, and for a fixed ring load location when the shell geometry is allowed to very. The influence of the buckling mode on the critical load is analysed. Numerical results are given for v = 0.3. |
