| 摘 要： | 用ANSYS软件对圆孔板的应力集中进行了有限元分析，计算了圆孔平板在单向或双向受力下的应力分布，并与理论解进行了比较，其ANSYS解与解析解均比较接近．同时，把在粗糙拱型下的计算结果和子模型下的结果进行了比较，从而论证了所用方法的优越性．

| Abstract: | The stress concentration of circle hole is analyzed in terms of finite element method by ANSYS software in this article. The stress of distribution of flat plates which have circle holes under unidirectional or bidirectional stress is calculated and compared with the analytic solution. Meanwhile, the results of calculation are compared with those obtained from the coarse model and submodel and the superiority of the approach is confirmed. |
