Abstract

Stress redistribution induced by excavation often results in tensile zones in the surrounding rock mass. It is of great theoretical and practical significances to analyse the localizations of deformation and damage and to study the complete stress-strain relation for mesoscopic heterogenous rocks under uniaxial tensile loading. Based on damage mechanics, the complete stress-strain relation, including linear elasticity, non-linear hardening, rapid stress drop and strain softening, is obtained. The rapids tress drop and strain softening are due to localizations of deformation and damage. The constitutive model, which analyzes the localizations of deformation and damage, is distinct from the conventional model, and theoretical predictions have shown consistency with the derived results.
