Gain-Frequency Characteristics for Several Models of Stratified Geological Medium
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 1
Abstract
Gain-frequency characteristics of displacements of daylight area at forced oscillations are studied. Several models utilizing a layer sitting on top of a basement are considered. Together with a classical model (considering two homogeneous media), investigated are a model for the layer with absorption and a model for the layer having continuous variation of elasticity parameters at transition toward the basement. The case of linear variation of density and a constant velocity is considered in detail. For all structures under consideration, analytical expressions for displacements of daylight area are obtained.
