摘要
讨论了弹性－幂强化材料厚壁球的安定性，研究了其在内压作用时的卸载规律和残余应力分布规律；在等向、随动两种强化模型情况下对厚壁球壳在循环内压作用下的安定分别进行了讨论，获得了球壳的安定载荷。
In this paper, the shakedown analysis of the thick-walled hollow sphere based on the elastic-power hardening model is discussed. The unloading and the residual stress distributions by the inside pressures are studied. Based on two kinds of the hardening models, the shakedown by cyclic inside pressures is discussed. The shakedown loads of hollow sphere are obtained.
