The difraction of plane elastic waves by a delaminated rigid inclusion when there is smooth contact in the delaminated region. (Q2714665)

The elastic medium under deformation contains a thin rigid inclusion located on the plane \(xy\) on the segment \(\,y=0\), \(\,| x| \leq a\). For \(\,y = -0\,\) the inclusion is connected with the elastic medium by the plane, while for \(\,y=+0\,\) it exfoliates. It is assumed that on the boundary the conditions of smooth contact are satisfied. The author proposes an approximate solution allowing the investigation of the stress near the inclusion and permutation under the falling wave impacts.
