Abstract:
The single-lap adhesive joint is among the most commonly used joint type in the industry. This is due to the simplicity and the ease for this type of joint to assemble. The single lap-joint application extends from the simple non-structural to the structural applications, where strength is an important consideration. For this reason, a good understanding of the adhesive behavior and the stress analysis of the joint is very important, especially for the overlapped bonded area in the lap joint. Study of Lap joint needs modeling, simulation and experimental validation. To verify the apparent strength of an adhesive Lap Joint several standard test methods are designed. One of the most commonly used test method is Lap Shear Test. This is a standard test method to test the apparent shear strength of a single lap joint that is adhesively bonded. The novelty of the present work is to study and discuss the modeling and simulation of interface delamination effect for adhesively bonded structures. For this purpose a simple case of lap joint is studied in the present work and finite element analysis (FEA) of the problem is investigated. An experimental verification of the simulated results is also presented and discussed. The study and understanding of such interface delamination phenomenon becomes more important between the layers of a composite structure and in case of composite joints.
