N2 - The interaction of an interfacial crack with small impurities is analysed on the basis of an asymptotic formula derived by the authors. The interaction between the main crack and the defects (e.g. small cracks or
inclusions) is described asymptotically by analysing the dipole ﬁelds and the corresponding dipole matrices of the defects in question. The method is generic, and it serves interfacial cracks with general distributed loading on the crack faces, taking into account possible asymmetry in the boundary conditions, and
in a particular conﬁguration for a crack in a homogeneous medium results agree with those obtained earlier by Gong [1]. Shielding and ampliﬁcation effects of the defects on the propagation of the main crack
along the interface are investigated. Numerical computations based on the explicit analytical formulae
show potential applications in the design of composite and ﬁbre reinforced materials.
