摘要
用库仑——莫尔屈服准则对厚壁球进行了极限分析。该分析能够较好地反映出考虑材料的拉压屈服强度不同而对结构极限承载能力的影响。结果表明 ,厚壁球的极限承载能力随着材料压拉比 K的增大而增大。本文导出的公式 ,对于理论研究和工程设计都具有参考价值。
In this paper, the limit analysis of thick hollow sphere is realized by using the Coulomb Mohr yield criterion. The influence of limit loading capacity for considering different tension and compression yield strength can be reflected thoroughly. The calculating results are given. From the results we know that the limit loading capacity of thick hollow sphere will be increased with the increasing of ratio of compression and tension. The derived formula in this paper is provided with important refernce value for theoretical research and engineering design.
