Abstract
In this paper a numerical investigation on the possibility to simulate and predict cyclic plastic response incorporating damage has been performed. To this purpose, unit cell and continuum approaches based on porous metal plasticity and continuum damage mechanics (CDM) have been considered. In particular, the porous metal plasticity model of Leblond, Perrin and Devaux (LPD model) and the CDM model developed by Pirondi and Bonora were used. Finite element (FE) simulations were performed for each approach with different degrees of triaxiality and the results are analyzed and compared.
