A material model for plain concrete formulated within the framework of multisurface elastoplasticity-damage theory is proposed in this paper. Anisotropic sti ness degradation as well as inelastic deformations are taken into account. The applicability of the model encompasses cracking as well as the

A two-phase coupled elastoplastic-damage model proposed by Ortiz (Ortiz M. Mechanics of Materials 1985;4:67Β± 93) for modeling inelastic behavior of concrete is considered. For integration of anisotropic damage evolution equations an implicit integration scheme is proposed and the resulting nonlinear
## Abstract A conceptual model for describing effective saturation in fractured hard rock is presented. The fracture network and the rock matrix are considered as an equivalent continuum medium where each fracture is conceptualized as a porous medium of granular structure and the rock matrix is ass
