摘要：This paper includes the analysis of the interactions of two coplanar elliptical cracks, with equal or different crack sizes, embedded in finite thickness plates under uniform tension. The ratios of crack depth to crack length (b(1)/a(1) and b(2)/a(2)) are 0.25 and 1.0; the relative distances between two cracks (s(1)/b(min) and s(2)/b(min)) range from 0.5 to 2.0. Two kinds of interactions, interactions 1 and 2, with a total of 42 crack configurations, are studied and the stress intensity factors along the crack front are presented. The numerical results show that interaction 2 has a stronger interaction than interaction 1. The numerical analyses are carried out by the hybrid boundary element method.
