Abstract

The Rayleigh wave velocity is examined in isotropic and non-isotropic auxetic (negative Poisson's ratio) solids. A novel approximation of the Rayleigh wave speed c versus the Poisson's ratio of an isotropic solid is derived using the concept of ellipticity. The Rayleigh wave propagation is investigated also for anisotropic incompressible solids, such as thick composite balanced symmetric cross-ply laminates, exhibiting through-the-thickness negative Poisson's ratio. The results show increased wave speed for auxetic laminate configurations, as well as increased sensitivity of the wave speed in the cross-ply regions corresponding to NPR values.
