| 摘 要： | 根据1种修正的余能原理，建立了具有1个无外力圆柱表面的12结点三维杂交应力元，其单元内的应力场满足三维柱坐标平衡方程及无外力圆柱面边界条件；当元退化为二维时，也满足协调条件。数值算例表明用这种特殊杂交应力元能十分有效地分析具有偏心圆孔厚（薄）板的三维及二维应力集中。

| Abstract: | A 12 node Special solid elements with a traction free cylindrical surface is derived using the assumed stress hybrid model. The a ssumed stress field satisfies the equilibrium equations in the element and the t raction free boundary condition over the cylindrical boundary. Numerical result s have indicated that the distributions of the circumferential stress and stress concentration factors in a thin plate or thick plate with eccentric hole under tension by the use of coarse meshes. |
