周边简支受均匀内压锥壳的塑性极限载荷

PLASTIC LIMIT LOAD OF CIRCULAR CONICAL SHELLS:ITS PERIPHERY FIXED WITH HINGES UNDER UNIFORM INTERNAL PRESSURE

本文应用能量原理,给出了锥壳处在塑性状态时的位移场,由于选择了线性速度函数u,v,w,因而使得在计算塑性功率时得到简化,求得较满意的上限解。

Applying the principle of energy, giving the displacement of circular conical shells in their plastic condition, and selecting the linear functions of speeds u, v, w, the plastic power can be calculated more simply and the satisfactory upper limit may be found.
