title: Rayleigh-Taylor linear growth at an interface between an elastoplastic solid and a viscous liquid.
abstract: A previously developed model for the Rayleigh-Taylor instability at an interface between an elastoplastic solid and a viscous fluid [Piriz, Sun, and Tahir, Phys. Rev. E 88, 023026 (2013)] has been used for calculating the time evolution of the perturbations in terms of the mechanical properties of the solid and the liquid, as well as of the initial amplitude ξ_{0} and the wavelength λ of the perturbation. Four kinds of possible evolution are found: two stable and two unstable, depending on their positions in the space of parameters (ξ_{0},λ). All of them present some features that are independent of the solid properties and that are determined only by the liquid viscosity.
