A simplified hardening cohesive zone model for bondline thickness dependence on adhesive joints
Source abstract
Abstract
In this paper, a tri-material adhesive system with nonlinear cohesive springs embedded between two elasto-plastic adhesive layers is proposed to predict the adhesive thickness effects on the fracture energy of bonded joints. The localized plastic and damage behaviours along the interface are described by the hardening cohesive zone models. The thickness dependent interfacial energy release rate is divided into the essential separation energy rate and the energy dissipation rate of the plasticization. The adhesive thickness dependent hardening cohesive zone model is implemented into the proposed numerical method to predict the failure of the adhesive joints. The validation of the model is performed by comparison with the experimental data.
