Explicit crack-tip fields of an extending interface crack in an anisotropic bimaterial. (English) Zbl 0735.73068
Summary: Explicit expressions for crack-tip fields of a crack, dynamically extending along the interface of an anisotropic bimaterial, are presented. The deformation considered is a combination of plane strain and anti-plane strain deformation. The amplitudes of the crack-tip fields are characterized by the stress intensity factors recently introduced by the author. The stress intensity factors due to dislocations and body forces for a steadily moving semi-infinite crack are derived and the weight functions for crack face loading are given.
