Asymptotic, plane strain near-tip fields are presented for steadily propagating interface cracks between (1) a ductile solid and a rigid substrate, and (2) two dissimilar ductile solids. The ductile materials are taken to be incompressible, elastic-perfectly plastic and obey the \(J_ 2\)-flow theory of plasticity. It is shown that the crack-tip region can be considered as being composed of two types of angular plastic sectors: uniform sectors, in which stresses are constant, and nonuniform sectors.
