Cohesive elements are useful in modeling adhesives, bonded interfaces, gaskets, and rock fracture. The constitutive response of these elements depends on the specific application and is based on certain assumptions about the deformation and stress states

The available traction-separation model in Abaqus assumes initially linear elastic behavior (see Defining elasticity in terms of tractions and separations for cohesive elements) followed by the initiation and evolution of damage. The elastic behavior is w

Cohesive Element Modeling in Abaqus Introduction Modeling the deformation and failure response of parts that are bonded together is one of the few FE topics that seem hard to do, but is in fact relatively simple to do one you know how to set it up.
