Title Edge Crack Opening in an Elastic Plane with a Wedge-Like Cut in Contact with a Punch
Author(s) V.I. Ostrik (Institute of Applied Physics, National Academy of Sciences of Ukraine, Petropavlovskaya†St.,†58, Sumy, 40030 Ukraine,
Abstract The equilibrium of an elastic plane with a wedge-like cut and an internal or edge crack on the symmetry axis was studied in [1] in the case of punch indentation in the lateral faces of the cut at a distance from the cut tip. In [1], the system of singular integral equations of the problem was solved numerically by the mechanical quadrature method.

In this paper, the generalized Wiener-Hopf method [2] is used to obtain the analytic solution of a similar problem in the case of an edge crack under punch pressure on parts of the cut lateral faces adjacent to the cut tip. Some special cases of this problem were considered earlier without a crack [3, 4] or a punch [5, 6].
