Krauklis, P. V.; Krauklis, A. P. The weak boundary effect in a field as a source approaches the boundary. (Russian, English) Zbl 1130.74023 J. Math. Sci., New York 132, No. 1, 48-55 (2006); translation from Zap. Nauchn. Semin. POMI 308, 89-100, 253 (2004). Summary: The response of a weak interface inside an isotropic elastic medium to an approaching source is considered. It is shown that a strong shear wave arises in the wave field reflected at an angle greater than a critical one. Properties of this wave are studied, and theoretical seismograms describing the contribution of all reflected waves to the total field are presented.
