The Simulation of The Process of Laminal Damage Using The Cohesive Interface Element
Laminal damage is a main type of damage in the adhesive bonded joint, and it often occurs in the interface layer of the joint. So, it is necessary to analyze the mechanical action of the interface layer. However, because the thickness of the interface layer is very small, it is difficult to simulate the interface layer by regular finite element method or boundary element method, and it is also difficult to simulate the process of laminal damage. To aim at this situation, we use the cohesive interface element with the thickness of zero to simulate the interface layer to get the rule of laminal damage, and contrast with experimental result to validate the validity of the method. By contrasting with experimental result, we find the result in the simulation is identical with the result in the experiment. So, the method of using the cohesive interface element to simulate the interface layer is effective.
