Abstract: Low-frequency approximation of elastic wave transmittance for two-layer structures is proposed. An accuracy of the approximation in a range up to several kilohertz is studied. Based on this approximation, the problem of the optimal elastic parameter choice for two-layer blast protection jackets is considered.

Keywords: two-layer structures, elastic waves, blast waves, blast protection.
