摘要
对一个复杂钢构件作了非线性有限元分析．利用子模型法，并考虑到接触问题，派生出３个子问题：接触分析、整体分析和子模型分析．最后获得应力严重集中区，即圆角区的应力应变分布状况．
A complex steel component is analyzed by nonlinear FEM. Applying submodel, and considering the contact between two members named bolt and breech, respectively, the analysis process is divided into three subproblems: contact analysis, global analysis and submodel analysis. The stress and strain distribution on breech ring fillet, the serious stressconcentration zone, are obtained. The softwares for calculation are IDEAS and ANSYS.
