摘要：This paper analyzes the interactions of two coplanar semi-elliptical surface cracks located, respectively, at the front and back surfaces in a finite thickness plate under uniform tension. Few numerical solutions appear to be available in the literature so far for this kind of interaction. The analyzed ratios of crack depth to crack length (b(1)/a(1), b(2)/a(2)) are 0.25, 0.5 and 1.0; the minimum relative distances between two cracks (s(2)/b(min)) range from 0.5 to 2.0. In total, 18 crack configurations are analyzed. The mode I stress intensity factors along the crack front and the interacting coefficient of two cracks are presented. The numerical analyses are carried out by the hybrid boundary element method. Copyright (C) 1996 Elsevier Science Ltd
