DISPERSION OF LAMB WAVES IN A THREE-LAYER PLATE MADE FROM COMPRESSIBLE MATERIALS WITH FINITE INITIAL DEFORMATIONS

摘要

A three-layer plate made from compressible elastic materials with finite initial deformations caused by compressive forces applied to their faces is considered. By using the three-dimensional linearized theory of propagation of elastic waves in bodies with initial stresses, the propagation of Lamb waves in this plate is investigated.
