The uniaxial constitutive law for an adhesive is studied by constant strain rate tensile, creep and relaxation tests. The S-D effect of the adhesive is taken into account by using the Raghava yielding criterion in a three dimensional constitutive formulation. The obtained constitutive law is then used to analyze a single lap joint and a butt joint by a finite element method. Constant cross head speed tensile and creep loading cases are examined. For a butt joint, the results show that the… 
Viscoelastic Analysis of Adhesively Bonded Double – Lap Joint
In this paper, stress distribution in a double lap joint subjected to a tensile load is investigated using the boundary element method. The adhesive used in this study is a commercial epoxy system
An Analytical-Numerical Approach Concerning the Stresses and Deformations in Single-Strapped Adhesively Bonded Joints
In this paper, starting from analytic relations presented in literature, a more general approach was obtained in order to evaluate the load capacity of single strapped joints in the cases when the
Rate-dependent shear deformation of ductile acrylic adhesive and its constitutive modelling
Recently, new types of structural adhesive with high ductility, as well as high strength, have been developed and put on the market. Such high ductile adhesives usually have strong rate sensitivity
Failure criterion for adhesively bonded joints using Arcan´s experimental method
Characterization of polymeric materials mechanical behavior requires some previous knowledge about their structure, which allows the choice of more appropriated models and methods. Polymeric
A nonlinear viscoelastic–viscoplastic constitutive model for adhesives under creep
In this study, we consider the nonlinear viscoelastic–viscoplastic behavior of adhesive films in scarf joints. We develop a three-dimensional nonlinear model, which combines a nonlinear viscoelastic
The Effect of Geometry and Material Properties on the Load Capacity of Single-Strapped Adhesive Bonded Joints
Adhesive bonding is a particularly effective method of assembling complex structures, especially those made from dissimilar materials. If the joint is well designed and correctly executed, the

This paper gives a bibliographical review of the finite element methods (FEMs) applied to the analysis and simulation of adhesive bonding, soldering and brazing processes. The bibliography at the end
Identification by Genetic Algorithm of a Constitutive Law Taking into Account the Effects of Hydrostatic Pressure and Speeds
Meeting technical specifications requires the improvement of polymeric material behaviour used in the conception of structural parts notably in the automotive sector. It is in this context that
Study on Vibration Suppression System Using Thin Film with Viscous Lamina
Passive damping augmentation is one of attractive methods for vibration suppression to various kinds of structures because it is definitely stable and generally simple. The system using thin film


Stress analysis of axisymmetric butt joints loaded in torsion and tension
Abstract Axisymmetric butt joints are widely used as specimens for testing the response of adhesives to shear and tensile stresses. When analysing the results from these tests, the stress
Viscoelastic Analysis of Adhesively Bonded Joints
In this paper an adhesively bonded lap joint is analyzed by assuming that the adherends are elastic and the adhesive is linearly viscoelastic. After formulating the general problem a specific example
The macroscopic yield behaviour of polymers
A yield criterion, not previously compared with the actual macroscopic behaviour of polymers, is herein compared with the pressure-modified octahedral shear stress criterion earlier suggested by
Predicting strength of adhesive joints from test results
Using an avarage-stress oriterlon can lead to errors of an order of magnitude in predicted load carrying capability of a bonded joint. A fracture mechanics approach is shown to accurately predict
