Analysis of the 'Joggle-Lap' Joint for Automotive Applications.

Abstract

An analytical model is developed to describe the response of the 'joggle-lap' joint to both tensile and bending loads. The model consists of a non-linear beam analysis which calculates stress profiles through the adherent thickness. A plane stress finite-element model was incorporated into the analysis to correctly determine the stress field in the adhesive zone where it was shown that beam analysis was less accurate. Elastic response of the 'joggle-lap' joint due to tensile loads was verified through experimental testing and ultimate loads were accurately predicted within experimental error. Maximum adherent flexural stress was found to determine joint failure. A parametric study was undertaken by using the verified analytical model and the results were recorded as a series of design curves.
