The calculation of an initial pre-fracture zone near the end of a crack in a piecewise homogeneous isotropic elastic body under plane strain by the Wiener-Hopf method is presented. The crack is located at the interface of media. The pre-fracture zone is modeled by the direct line of the normal displacement rupture emerging from the end of the crack. The dependences of the pre-fracture zone length and the slope angle on the load and other parameters of the problem are investigated.
