Asymptotic elastic fields near an interface anticrack tip

Using analytic continuation, we derive the asymptotic elastic fields associated with a fixed, semi-infinite anticrack lying on the interface between two dissimilar elastically isotropic half-planes. We derive the two pairs of analytic functions defined in the two half-planes which characterize the elastic fields of stresses and displacements in the bimaterial. The negative anticrack contraction force is expressed in terms of the established complex stress intensity factor.
