Title: Modelling of Concrete in Tension - Energy Dissipation in Cyclic Loops

Abstract:This paper deals with modelling of concrete subjected to cyclic loading in tension. A model based on the theory of plasticity combined with the theory of damage mechanics was developed. To describe the non-linearity that concrete exhibits during cyclic loading, the concept of bounding surface is used as a hardening function. An evolution law for the elastic domain is proposed that depends on the consumption of fracture energy in hysteresis loops. In addition, an energy balance equation is proposed, which deals with the consumption of fracture energy by completing hysteresis loops. Finally, a drawback in the smeared crack approach for combined damage and plasticity is identified and presented.
