Abstract

Majority of automobile and aerospace parts, mainly their body components are joined together by different types of adhesives. So these growing needs demand the detailed study on stress concentration and strength analysis of adhesive joints.[39] With the help of structural analysis simulations we can identify the problem areas, failure loads and solutions can be validated in computers without any expensive shop floor operations prior to any tool construction.[40] Structural analysis simulation is also helpful at the joint design stage to decide various parameters, like adhesive thickness, overlap length, overlap area and load applied etc. In the recent years the use of finite element analysis is increased in the strength analysis of sheet metal joints. Finite element analysis helps to analyse the process virtually. The present work reports a detailed investigation of a stepped lap adhesive joint with similar metals. This joint is subjected to static tensile loading and the ANSYS software package is used to carry out the analysis. The analysis results helps in depicting the effects of varying load, adhesive thickness, overlap length and overlap area on stress induced and hence on the joint strength. The metal to metal stepped lap adhesive joint specimens using Aluminium as adherend and AralditeĀ® as adhesive under gradually applied static tensile loading are tested on UTM and the results obtained by FEA are validated.
