Determination of the physicomechanical characteristics of viscoelastic materials in orthotropic and isotropic layers from the propagation velocities and damping constants of longitudinal and shear vibrations

  • 19 Accesses

Abstract

The author examines the propagation of longitudinal and shear waves in viscoelastic orthotropic and isotropic layers. Relations are obtained for determining the elastic constants and the real and imaginary parts of the complex moduli and Poisson's ratios in orthotropic and isotropic layers from the propagation velocities and damping constants of longitudinal and shear vibrations.
