Abstract
We perform calculation of the initial prefracture zone at the tip of a mode I crack that reaches a nonsmooth interface of two dissimilar elastic media at its corner point by the Wiener–Hopf method The zone is modeled by a line of normal displacement fracture on a crack continuation Expressions for the length of the prefracture zone and the potential energy accumulated in it are obtained Their numerical values are compared with the corresponding values for the prefracture zone in a bonding material on the interface of the media on the basis of which we draw a conclusion on the possible direction of development of the zone
