Original abstract
The paper presents the results of the research determining the impact of structural modifications of adherends on the load capacity of the joints determined in the static shear test. Tests of adhesive lap joints of S235JR steel sheets bonded with Araldite 2014-2 epoxy adhesive are described. The influence of technologically simple structural modifications was investigated, consisting in making notches and holes at the leading edge of the ad-herends. These modifications were aimed at bringing about local flexibility of the joint in the sensitive area of stress concentration. Based on experimental studies, it was shown that there is a possibility of increasing the load-bearing capacity of the joint due to the applied modifications, in the most favorable variant, an increase in the load-bearing capacity by 15.9% compared to the base variant was demonstrated. The tests confirmed that filled notches by the adhesive in the front part of the adherends can significantly improve the strength properties of joint, while the considered modifications in the form of holes do not have a significant impact on the proper-ties of the adherends.
