Coupled Elastic-Softening Joint Model

The implemented contact constitutive model is an extension of the Fracture Energy Softening Model where the pre- and post-peak behavior of cohesive quasi-brittle materials subjected to various loading conditions is predicted via proposed fracture energy-based bi-linear elasto-softening behaviour.
