Axial compression welding hollow ball node wall fitting surface stress formula

摘要

This paper mainly studies the hollow spherical wall in axial compression, considering the effects of weld, hoop stress range change in space and its regularity. This article USES the ANSYS program of hollow wall outer wall and middle tier wall are carried out in stress analysis, the finite element software computing results, comparing with the results of mechanics of elasticity formula of hollow spherical wall ring correction to stress in a reasonable manner to establish wall hollow hoop stress at different axial compression condition under the range of stress formula.
