Resumen:
A damage-plasticity constitutive theory for zero-thickness interfaces is presented aimed at predictingtime-dependent self-healing phenomena in concrete. The material model is based on fracture-energyconcepts and accounts for the time evolution of concrete porosity induced by the self-healing mechanism.The accuracy and soundness of the proposed interface model are demonstrated through comparativeanalyses of model predictions against experimental results on three point beam tests performed upto crack opening and then, up to complete failure, before and after been subjected to different exposureconditions, respectively. A wide range of experimental tests was considered in this work for both calibrationand validation purposes of the proposed interface model.
