Abstract

Diffractions of elastic waves by a circular inclusion with a nonhomogeneous interface layer are studied by using the wave function expansion method. The effective complex wave numbers follow from the coherent wave equations and the effective elastic moduli can be obtained from the phase velocities of the coherent waves. The dynamic stress concentration factors are found to be dependent on the circular frequency, the interface properties and the composite material properties, and, at certain circular frequencies, they are larger than those encountered under statical loading.
