Small Amplitude Plane Waves in Deformed MooneyRivlin Viscoelastic SolidsDipartimento di Ingegneria dellInnovazione, Sezione di Ingegneria Industriale, Università di Lecce, 73100 Lecce, Italy A homogeneous isotropic incompressible viscoelastic material of differential type whose elastic part of the stress tensor is modelled through the use of the MooneyRivlin from of the stored energy function, and whose dissipative part is modelled as in a Newtonian fluid, is maintained in a state of finite static homogeneous biaxial deformation. The equations of superimposed infinitesimal motions on the finite deformation are derived. All propagating homogeneous and inhomogeneous solutions are given, as well as the conditions for linear, elliptical, or circular polarization.
Key Words: nonlinear viscoelasticity bivectors inhomogeneous waves
