# Porous metal plasticity

 The porous metal plasticity model: is used to model materials with a dilute concentration of voids in which the relative density is greater than 0.9; is based on Gurson's porous metal plasticity theory (Gurson, 1977) with void nucleation and, in Abaqus/Explicit, a failure definition; and defines the inelastic flow of the porous metal on the basis of a potential function that characterizes the porosity in terms of a single state variable, the relative density.
