Modeling of porous materials with isotropic-kinematic hardenable matrix under cyclic loading

Abstract eng:
The main objective of this work is to investigate the response of the ductile porous material subjected to cyclic loading. To this end, by adopting the non-linear homogenization theory proposed in [2], we first formulate a new constitutive model for porous materials with hardenable matrix. An isotropic hardening law as well as kinematic one are considered. The resulting elasto-plastic model at macroscopic scale is then numerically implemented based on the algorithm described in [1]. Finally, the prediction of the proposed elasto-plastic model is validated by comparing with the Finite Elements results.
