On the Toughness of Ductile Adhesive Joints
Crack propagation along one of the interfaces between a thin ductile adhesive layer and the elastic substrates it joins is considered. The layer is taken as being elastic-plastic, and the fracture process of the interface is modeled by a traction-separation law, characterized by the peak separation stress 6 and the work of separation per unit area To. Crack growth resistance curves for mode I l...
متن کاملFracture Analysis of Adhesive Joints Using Intrinsic Cohesive Zone Models
In this paper Cohesive Zone Model (CZM) concepts are applied in order to study mode I fracture in a pre-cracked bonded Double Cantilever Beam (DCB) specimen. A cohesive surface element is implemented in a Finite Element commercial code using intrinsic cohesive zone models: exponential, bilinear and trapezoidal traction-separation laws. The sensitivity of cohesive zone parameters in predicting t...
متن کاملEffects of substrate material on fracture toughness measurement in adhesive joints
To understand the effects of substrate materials on the fracture behavior of adhesive joints, experimental studies and finite element analyses have both been conducted for double-cantilever-beams (DCB) with aluminum and steel substrates at different bond thickness (h). Numerical results show that the region dominated by the crack singularity is much smaller than the bond thickness. Very small p...

متن کاملMixed Mode Fracture Toughness of an Adhesive Bonded Joint
Adhesive joints are continuously emerging as candidate to replace traditional fastening systems, such as riveting or welding, in primary structural applications. A wide class of components belonging to electronic, automotive and aerospace industries contains adhesive joints, however, the reliability during service constitutes a major technical problem as these contain flaws. Therefore, their us...
