Abstract

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 region) is approximated by a finite number of guided wave modes. Matching at the interface between the two regions is obtained by satisfying the stress and displacement compatibility conditions. Numerical results showing the effects of cracks in a plate, in the form of changes in spectra and pulse shapes of the displacements on the surface of the plate, are presented.
