Abstract
Structural adhesively bonded joints are frequently used in many areas spearheaded by the industries such asautomotive, marine space, and aviation due to the great advantages they provide. Besides, load capacities ofadhesively bonded joints which have different geometries, are generally determined experimentally. Beingcompatible of experimental and numerical analysis of adhesively bonded joints in the means of both load carryingcapacity and displacement has a great importance. But, one of the most common problems in comparison ofexperimental and numerical analyses is in spite of the coherence of experimental and numerical analyses in loadcarrying capacity, it is observed that in the means of the displacement analysis, there is incompatibility betweenthose analyses. In the present study, force-displacement curves of the single-lap cohesively bonded joints areobtained experimentally by using both strokes of two different tensile test machines which have identicalcalibrated load cells and video extensometer. Experimentally obtained result was compared with numericalanalysis. In the experiments, AA2024-T3 aluminium and two-component Araldite 2015 were used as adherendand adhesive, respectively. As a result, there is considerable difference between the force-displacement curvesof the single-lap overlap joints which obtained experimentally from stroke and video extensometer. Also, beingnew or old of the tensile test machines which have identical calibrated load cells varies the displacement curve ofthe joint. When the experimental data were compared with the results of the numerical analysis, it is concludedthat, obtaining the force-displacement curves of joints by using video extensometer is more accurate.
