Ahstract-A hybrid finite element method is proposed for the analysis of guided wave scattering in a plate containing multiple subsurface cracks at arbitrary orientations. A part of the plate around the cracks (interior region) is modeled by conventional finite elements. The far-field (exterior regio

The diffraction of a plane flexural wave by a through-the-thickness crack in an elastic plate is examined by application of Mindlin's theory of flexural motions of plates. In his theory, which takes into account the rotatory inertia and shear effects, an incident flexural wave passing through the cr
The diffraction of flexural waves by a short straight crack in an elastic thin plate is considered. The vibrations of the plate are described by the Kirchhoff model. The Fourier method transforms the problem to integral equations of convolution on an interval. The theorems of existence and uniquenes
This work presents a numerical algorithm for solving crack scattering in a transversely isotropic medium whose symmetry axis is perpendicular to the crack surface. The crack is modelled as boundary discontinuities in the displacement u and the particle velocity v, of the stresses [ u# v], where the
