| Abstract: | We study the interaction of a magnetoelastic shear wave with a curvilinear tunnel crack in an ideally conducting diamagnetic
(resp. paramagnetic) one-sided (resp. two-sided) layer in the presence of an external static magnetic field. The bases of
the one-sided layer are free of mechanical load, and the rim of the face is clamped or free. The corresponding linearized
boundary-value problem of magnetoelasticity is reduced to a singular integrodifferential equation with subsequent implementation
on a computer. We give numerical results that characterize the influence of the size of the preliminary magnetic field, the
frequencies of the load, the curvature, and the orientation of the crack on the stress intensity factor.
