Thermomechanically Consistent Continuum Damage Model for Concrete Materials
Publication: Journal of Engineering Mechanics
Volume 123, Issue 1
Abstract
Concrete is a highly heterogeneous multiphase material, and its constitutive and damage behavior has some very special characteristics. In this paper an elastoplastic constitutive relationship is proposed for damaged concrete materials based on a thermomechanically consistent mechanical model. The proposed relationship takes into account the interaction between volumetric and deviatoric inelastic deformation, hardening, anisotropic damage, unilateral effect of damage, and different failure modes. The validity of the proposed model is verified by comparing theoretical and experimental results of concrete subjected to triaxial stress histories with strain-controlled cyclic loading and unloading.
