Finite element analysis of elastic contact problem of axisymmetric opening in spherical shell 球壳开口轴对称弹性接融问题有限元分析
As hole-intensive, it will cause stress concentration on the local area after opening; stress on local area reaches its yield possibly under changes in the status of the furnace and the corresponding fluctuations of the furnace shell in the circumstances, which entered the plastic state. 由于孔洞密集,开孔后在局部区域会引起应力集中;在炉况变化、炉壳受力相应波动的情况下导致局部区域应力可能会提前到达屈服,从而进入塑性状态。
