| 中文摘要: |
| 本文提出了一组应力函数,采用边界配置方法计算了含中心裂纹不同截面形状柱体扭转时的应力强度因子。有关椭圆截面柱体的算例表明,本文方法具有良好的精度。同时,文中给出了圆、椭圆和矩形等不同截面柱体的计算结果。 |
| 英文摘要: |
| In this paper a set of stress functions has been proposed, and the boundary collocation method is used to obtain the stress intensity factor (SIF) of a torsional bar with an arbitrary section and a central crack. The examples for the elliptical sections show that the present method has very good accuracy. At the same time, a series of results for the cylindrical, elliptical and rectangular sections are obtained. |
