Abstract

Recent research into the effect of adherend thickness on the pull-off strength of adhesively bonded joints revealed that the pull-off strength increases with panel thickness, and prediction of this phenomenon needs an empirically determined characteristic distance in conjunction with the modified Drücker-Prager/cap plasticity material model. This paper presents an improved approach for capturing this adherend thickness effect using a cohesive element approach. The influence of cohesive law shape on the predicted strength is presented, with the results showing that a non-softening cohesive law provides the best predictions of joint strengths.
