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

The present paper proposes a constitutive theory for concrete based on the geometry of its mesostructure and the actual kinetics of the microcrack evolution. The only material parameters used within the context of the proposed formulation are those associated with the elastic, macroscopic response a
Scalar damage models are very often implemented in computational analyses in order to predict the response and failure modes of concrete and reinforced concrete structures. In most situations, however, damage is not isotropic but has preferential directions. Therefore, there have been many questions
Estimation of the stress-strain relationship for concrete in uniaxial tension is done by means of a semiempirical damage model. The damage is a measure of the relative portion of pores and cracks in the material. The model is related to stress-strain curves published by Evans and Marathe (3). ##
