拉压异性线性等向强化材料厚壁球壳极限分析

LIMIT ANALYSIS OF THICK WALL SPHERICAL SHELL OF LINEAR HARDENING MATERIAL WITH DIFFERENT YIELD STRENGTH IN TENSION AND COMPRESSION

  • 摘要: 运用Mohr屈服准则对承受内压的拉压屈服强度不同的线性等向强化材料的厚壁球壳进行了极限载荷分析, 得到了依赖于拉压比和强化模量的厚壁球壳极限载荷解析式和依赖于拉压比和强化模量的厚壁球壳极限载荷分析式.结果表明,材料拉压屈服强度的不同和强化特性对厚壁球壳极限载荷均有一定的影响.

     

    Abstract: This paper presents the limit analysis of thick wallspherical shell of linear hardening material with different yield strength intension and compression based on the Mohr's yield criterion.The analytic expressions of stress distribution in the elastic andplastic deformation area are obtained.The analytic expression of the limiting pressure with respect to theparameter αis also obtained by the analysis.The theoretical analysis shows that the different yield strength of thematerial in tension and compression will influence the limitedpressure of thick walled spherical shell.
