Shear waves due to cracks in an isotropic rectangular strip

A mathematical formulation of the shear waves due to the presence of a crack, loaded in an opening mode, in an isotropic and elastic rectangular strip is presented. An analytical solution based on application of spectral representation and Green's functions methods is developed. Numerical presentations of the solution demonstrate the effect of crack length on the amplitude of these waves at any given position along the sides of the rectangular strip. The solution provides a quantitative analysis on means of detection of shear waves emitted due to the presence of a loaded crack.
