Abstract
Concrete is the main construction material used for infrastructure construction around the globe. Since it is a brittle material, applied loads on concrete structures will result in sudden failure of the structure, and consequently the service of the structure will be affected. To prevent such failure, it is necessary to understand and predict the behavior and failure mechanics of concrete. Recently, the concept of the cohesive zone model has been widely applied to investigate various material failure phenomena. The potential-based model has advantages over the non-potential-based cohesive model in that their traction-separation relations are determined by taking the derivative of potential (cohesive interaction) concerning normal and tangential opening displacements. The purpose of this study is to evaluate the application of potential-based cohesive model for the study of concrete fracture by employing a user element in ABAQUS. The simulation is compared with reproduced experimental results and good agreement has been found between load-displacement curves.
