Scattering of in-plane compressional (P) and shear (SV) waves by a polygonal inclusion is studied by using the boundary-element method. We apply the results of the single scattering problem to the propagation of elastic waves in a composite containing a dilute concentration of polygonal inclusions. Numerical calculations are carried out for a moderately wide range of frequencies, and the effect of inclusion shape on the scattering cross sections, and the phase velocities and attenuations of coherent waves and the effective elastic moduli for a dilute composite are shown graphically.
