摘要
应用 ANSYS软件对圆孔板的应力集中以及平板中心裂纹、圆孔板孔边裂纹进行了有限元分析 .计算了圆孔平板在单向或双向受力下的应力分布以及中心裂纹、孔边裂纹的应力强度因子 ,并与理论解进行了比较 ,其 ANSYS解与解析解均比较接近 .
The stress concentration of circle hole and the stress distribution for cracks adjacent to the hole were analyzed in terms of finite element method by ANSYS software in this article.The stress distribution of flat plates,that has circle hole under unidirectional or bidirectional stress, and the stress intensity factors of cracks or those adjacent to circle hole were calculated and then compared with the analytic solution.
