Summary

The propagation of elastic harmonic waves through a stratified slab is investigated. It is assumed a nonzero angle of inclination of an incident wave. The equations for the amplitudes of reflected and transmitted waves obtained in reference [1] are transformed to a form more convenient for numerical calculations and generalized for more complicated laminates. an example of the elastic waves propagating through the steel-titanium laminate in aluminimm environment is studied numerically. The limiting case where the density of stratification of the slab tends to infinity is analyzed. The dependence of the effective reflection properties on the material parameters of the strata is presented.
