description Today's modern automobiles are designed in a way that they must be light as well as safe, which refers to the adhesive joints as an assembling technique that meets both requirements. Energy absorption is originated from the adherend plasticity and adhesive layer in the adhesive joints. Thin adhesive layer is not expected to contribute too much to the absorption whereas the adherends could be the main source for this purpose depending on their mechanical properties, dimensions and loading mode. This study aims to focus on the design of adhesively-bonded Single Lap Joints (SLJs) under quasi-static compressive loading mode that would provide relatively high strength as well as high energy absorption, compared to those under the tensile load. To gain a deep insight in the mechanics of damage progression in the SLJs under buckling loading conditions, initially, joints with varying adherend thicknesses and overlap lengths were tested under compressive loads. The advanced 3D FE model was then created using Abaqus/Standard and validated against experimental results, confirming the accuracy of the predicted load-displacement curves. Examining the initiation and progression of damage in the compressed joints offered insight into relevant failure mechanisms. Increasing adherend thickness from 4 mm to 6 mm boosted energy absorption by over 80%, highlighting its greater influence compared to overlap length.
