Analysis of the “Joggle-Lap” Joint for Automotive Applications

Source

An analytical model was developed to describe the response of the “joggle-lap” joint to tensile loads. The model consisted of a combination of Euler, curved, and layered beam analysis which calculated stress profiles through the adherend 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 adherend flexural stress was found to determine joint failure. Fracture locations occurred within the adherend, outside the adhesive zone, primarily due to joint geometry.
