Adhesive joints are one of the most important joints in the industry of fixed joints. Due to its good advantages and being economical in terms of cost and time, more attention is paid to its use in all matters of human life, especially in the air, sea and land transportation industry. Because of the same tension on the surface of adhesives and non-homogeneous connections and small and large, thin and thick adhesive parts, more attention is paid to it every day. Increasing the strength, resistance and toughness of adhesive joints is a category. which has attracted the attention of scientists and researchers in the industry of adhesive joints, which is discuss in this research.
In this thesis, the effect of thickness in adhesive joints under static and impact loading was tested on aluminum alloy 7075 adhesive joints with a thickness of 5 mm, which is very strong and light, and End Fest 300 epoxy adhesive, which is a strong adhesive. and strong has been used in the industry of adhesive joints. In the static test, the best thickness of 0.5 mm against the force of 300 newtons is the highest strength and resistance and the displacement ratio of half a millimeter per minute. In the impact test, the best thickness of 0.5 mm has the highest force, which is 2811 newtons, and has more resistance and strength compared to other adhesive thicknesses. After that, thicknesses of 0.25, 0.8 and 1.1 respectively, which have the most strength and endurance in impact and static loading. Finite element simulation has been done in Abaqus software for the accuracy and reliability of the experiments.
