(2001) Effect of bond thickness on fracture behaviour in adhesive joints. To study the effects of bond thickness on the fracture behaviour of adhesive joints, experimental investigation and finite element analysis have been carried out for compact tension (CT) and double-cantilever-beam (DCB) specimens with different bond thickness. Fractography and fracture toughness exhibited apparent variati...

A mode-dependent embedded-process-zone (EPZ) model has been developed and used to simulate the mixed-mode fracture of plastically deforming adhesive joints. Mode-I and mode-II fracture parameters obtained from previous work have been combined with a mixed-mode failure criterion to provide quantitative predictions of the deformation and fracture of mixed-mode geometries. These numerical calculat...

An interface constitutive model which accounts for both reversible elastic, as well as irreversible inelastic separation-sliding deformations at the interface prior to failure has been developed and implemented in a finite-element computer program. A set of experiments has been conducted to determine the constitutive parameters in the interface model for adhesivelybonded components made from an...

A numerical study of the elastic-plastic mode-II fracture of adhesive joints is presented in this paper. A traction-separation law was used to simulate the mode-II interfacial fracture of adhesively-bonded end-notched flexure (E.N.F.) specimens loaded in three-point bending, with extensive plastic deformation accompanying failure. The fracture parameters for the traction-separation law were det...

The inherently low surface energy of carbon fibre reinforced Polyether-ether-ketone (CF/PEEK) composites results in an extremely compatibility with adhesives. This subsequently causes significant challenges the adhesive joining them to other dissimilar materials. Herein, bonding surfaces CF/PEEK were treated by a high-power UV-irradiation technique prior bonding, attempt develop hybrid composit...

New interconnection materials are always necessary as a result of evolving packaging technologies and increasing performance and environmental demands on electronic systems. In particular, anisotropic conductive adhesives (ACAs) have gained popularity as a potential replacement for solder interconnects. Despite numerous benefits, ACA-type packages pose several reliability problems. During the l...

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...

Almost all structural applications of adhesive joints will experience cyclic loading and in most cases this will irregular in nature, a form of loading commonly known as variable amplitude fatigue (VAF). This paper is concerned with the VAF of adhesively bonded joints and has two main parts. In the first part, results from the experimental testing of adhesively bonded single lap joints subjecte...

This study evaluated the effect of multiple consecutive adhesive resin coatings of adhesive bonded to human dentin on nanoleakage and resin-dentin bond strength. Resin bonded dentin specimens were prepared using a total-etch adhesive (One-Step Plus) applied as multiple consecutive coating, or using two self-etch adhesive systems (iBond or Fluoro Bond). For the total-etch adhesive, resin applica...
