Brittle Ductile Failure Mechanics of Mortar and Concrete

Abstract

This report summarizes analysis and results comprising both theory and experiments related to modeling of interfaces between cement matrix and aggregates. The model simulates accurately behavior under complex two and three dimensional states of stress and deformation, where tension-shear and compression-shear conditions occur. The constitutive theory describes fracture and slip of interfaces and adhesion, debonding, and mobilized friction mechanisms are modeled. Fracture energy release is used to control softening. Analytical predictions of experiments compare well, and the model has been implemented in nonlinear finite element analysis codes.
