Numerically, the damaged zone can be identified by the marking of the elements for which a criterion of rupture is exceeded. The analysed adhesive is a ductile adhesive. Therefore, the failure criterion used for cohesion damage of the adhesive layer is equivalent to the Von Mises deformation criterion.
