On the formulation of closest-point projection algorithms in elastoplasticity. PartI: the variational structure
Armero, F; Pérez Foguet, Agustí (Wiley and Sons, 2002-01)
Article
Accés obertWe present in this paper the characterization of the variational structure behind the discrete equations defining the closest-point projection approximation in elastoplasticity. Rate-independent and viscoplastic formulations ...
