Donato, Andrea and Palumbo, Annunziata (2000) Waves features related to a mathematical model of hypoplasticity. Memorie scientifiche di Andrea Donato, LXXVII.
We consider model equations describing the two-dimensional deformation of an incompressible elastoplastic material with constitutive laws of rate type. By introducing suitable potentials, we are able to write the system in equivalent forms which are suitable in order to study the propagation of discontinuity waves. By requiring the system to be linear degenerate we are able to characterise a simple model with a special constitutive law
