Аннотация: The results of computer simulation taking into account the linear and nonlinear material constants have been presented. Study of the influence of external uniaxial mechanical stress on the dispersive characteristics of elastic waves in piezoelectric structures as "La3Ga5SiO14/fused silica" has been executed. The comparison of elastПоказать полностьюic wave velocity changes under the influence of an uniaxial stress while a full set of nonlinear material constants of crystalline layer + geometric nonlinearity, or only geometric nonlinearity of the layer induced by the static deformation of a substrate, has been fulfilled.
