This paper considers the bonded joint as a multilayer structure that is analysed using the Transfer Matrix method. In this particular case three layers (two adherents and the adhesive) are considered. The study of this propagation problem may be developed from matrix formulations which describe elastic waves in layered media. This technique combines the theory of the dynamics of the continuum w...

A mesh independent continuum damage model has been proposed to predict the residual strength of adhesively bonded joints by introducing a displacement-based damage parameter into the constitutive equation of damaged materials. Joints bonded with a ductile adhesive EA9321 were studied for a range of environmental degradation. The moisture dependent damage parameter for EA9321 was calibrated usin...

An aerospace structure is built from the assembly of structural sub-components involving joining technologies such as welding, mechanical fastening or adhesive bonding. The function joints to ensure load transfer between sub-components. integrity directly depends on strength these joints. In order design critical areas, must be assessed. objective this review paper present approaches for simpli...

Three-dimensional finite element models are developed to investigate the effects of both tensile load and uniform temperature load on the stresses in hybrid joints. During the solution of the problem, finite element method (FEM) is preferred, as this method is very suitable for solving many engineering problems. An aluminum sheet is bonded a composite sheet. Hybrid joints are designed from both...

Experimental and numerical investigations were carried out on adhesively bonded full-scale double lap joints from pultruded GFRP profiles with relatively thick adhesive layers, needed in infrastructure applications to compensate for tolerances. The influence of different geometrical parameters on the joint strength was investigated, namely the thickness of the adhesive layer (from 5 to 35 mm), ...

This paper investigates the directional stability of crack propagation in adhesively bonded joints. First, an analytical model analyzing the energy balance during the crack propagation in double cantilever beam (DCB) specimens is presented, and the directional stability of cracks is predicted. The results are consistent with the analytical predictions made by Fleck, Hutchinson, and Suo [1] usin...
