摘要
本文研究了计算半随圆表面裂纹应力强度因子的边界元方法.文中提出了奇异等参元的合理布置,计算了内壁和外壁具有半椭圆表面裂纹圆筒的应力强度因子.
In this paper, the boundary element method for calculating surface crack is studied and suitable location or the singular isoparametric elements,is presented. The stress intensity factors of an internal and external semi-ellipticalsurface Crack in a cylinder are calculated.
