Two classes of exact solutions in the linear elastodynamics of transversely isotropic solids

Due to the formal resemblance of some models for the Cauchy stress tensor of elastic solids and viscous fluids, some classes of exact solutions for the equations governing the flows in Navier-Stokes fluids have been generalized to linear and nonlinear elastodynamics. In this paper, we study the conditions under which two special classes of generalized Beltrami flows, the vortices in lattice form and Kelvin's cat's eye solutions, are solutions of the equations governing the motions in a linearly elastic transversely isotropic solid.
