Analysis of adhesive-bonded single-lap joint with an interfacial crack and a void
void within the adhesive. Depending upon the number of notches and voids, the specimen is divided into several regions. Assuming that a plane strain state of deformation prevails in the specimen, we write the balance of forces and moments for each section and impose the continuity of displacements, forces and moments at the interfaces between the adjoining sections. By taking the Laplace transf...
متن کاملEvaluation of Fatigue Damage in Adhesive Bonding: Part 2: Single lap joint
Damage parameters for crack initiation in Single Lap Joint (SLJ) are determined by combining continuum damage mechanics, Finite Element Analysis (FEA) and fatigue experimental data. Even tough SLJ has a simple configuration; the stresses in the adhesive region are quite complex and exhibit a multi-axial state. Such a condition leads to the need to introduce a general value of triaxiality functi...
متن کاملAdhesive Bonding Lap Shear Strength Improvement of Cfr(peek) Laminates by Surface Morphology Modifications
In this paper, an experimental study concerning the effect of surface morphology on mechanical properties of adhesive bonding behaviour of continuous carbon fibres reinforced PEEK was performed. Surface morphology of PEEK composite was varied by sandblasting process. 3D morphological parameters were calculated from interferometry measurements. Surface wettability behaviour was studied by depose...
متن کاملThe Effect of Fiber Breakage on Transient Stress Distribution in a Single-Lap Joint Composite Material
In the present study, the transient stress distribution caused by a break in the fibers of an adhesive bonding is investigated. Transient stress is a dynamic response of the system to any discontinuity in the fibers from detachment time till their equilibrium state (or steady state). To derive the governing dynamic equilibrium equations shear lag model is used. Here, it is assumed that the tens...
متن کاملSemi Analytical Transient Dynamic Analysis of Composite Adhesive Single-lap Joints
A novel semi analytical method is developed for transient analysis of single-lap adhesive joints with laminated composite adherends subjected to dynamical loads. The presented approach has the capability of choosing arbitrary loadings and boundary conditions. In this model, adherends are assumed to be orthotropic plates that pursuant to the classical lamination theory. Stacking sequences can be...
