Dynamic responses of adhesively bonded tubular joints subjected to a harmonic axial load were evaluated with the use of a shear lag model. Adherents were assumed to be elastic and the adhesive was taken to be a viscoelastic material. Effects of tubular joint geometries, material properties and adhesive properties on the dynamic response of the system were investigated. The results showed that t...

Damage in single lap joints under shear load was assessed. Specimens were tested accordance with ASTM D1002-10(2019). Controls taken on adhesive and surface preparation, thickness, load-specimen alignment. Digital Image Correlation used to measure stresses over the adhesive, modulus variation percent of damage Results show losses against stress. Finally, early evolution determined up 10% rate l...

adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. on the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. the scope of this paper is experimental investigation on the effects of the addition of alpha-alumina nanoparticles to the ...

Abstract This study investigates the fracture onset and crack deflection in multi-material adhesive joints with thick bond-lines ( ? 10  mm) under global mode I loading. The role of adherend-adhesive modulus-mismatch pre-crack length are scrutinized. parameters controlling path directional stability also discussed. Single-material (i.e. steel-steel GFRP-GFRP) bi-material steel-GFRP) double-cant...

Because composites and adhesive joints are made from different phases with different thermal expansion coefficients, they inevitably develop residual thermal stresses. When designing composites or adhesive joints, it is important to account for these residual stresses. It is not the magnitude of the residual stresses that matters, but rather the effect of those stresses on composite failure pro...

Mixed-mode fracture of an adhesively-bonded structure made from a commercial adhesive and a dual-phase steel has been studied under different rates. Since mixedmode fracture occurs along the interface between the steel and adhesive, the cohesiveparameters for the interface were required. The mode-II interfacial properties were deduced in earlier work. In this paper the mode-I interfacial toughn...

Synovial chondromatosis is a rare benign lesion originating from the synovial membrane. It presents as adhesive or non-adhesive intra-articular cartilaginous loose bodies. Although the causes of synovial chondromatosis have not been fully elucidated, inflammation, external injury, or excessive use of joints have been suggested as possible causes. Synovial chondromatosis has been reported to occ...

The failure in structural adhesively bonded lap joints can be analyzed following different approaches: using a nominal stress state typically given by Strength of Material models, a local singular stress state induced at the mutimaterial corners of the joint, or using cohesive constitutive laws for the adhesive layer or other damage progression models. The aim of this paper is to analyze the su...

Kissing bonds are adhesive bonding defects and are thought to arise from either contamination of the surfaces during manufacture or various forms of environmental attack. . When adhesives are used for safety critical applications the current method is to undertake extremely careful process control. None-the-less premature failure of adhesive joints still occurs and kissing bonds are often the m...
