Straight Crested Waves in an Infinite Linear Viscoelastic Plate Using the Standard Linear Solid Model and Assuming Constant Poisson'S Ratio

摘要

The problem of straight crested waves propagating in an infinite plate composed of a linear viscoelastic material is examined. It is found that, for the assumption of constant Poisson's ratio, the roots obtained for Rayleigh's characteristic equation for the infinite elastic plate can be used to determine the damping and frequency of oscillation in the viscoelastic case. The standard linear solid is used to represent the material's behavior in shear. A particular example is given for polyisobutylene. (Author)
