Abstract: In this study, the effects of epoxy adhesives (Tra-Con F113, Hysol 9361, Epotek 301-2) which are used to fill thin-walled tubes are deformation, specific energy absorption (SEA) capacity, maximum crushing The load and size of the thin-walled aluminum tubes with different circular sections (circular) and 2 mm thickness are studied both numerically and experimentally. The aluminum tubes were made in the same thickness, height, average sectional area and material and were subjected to axial quasi-static loading by the INSTRON apparatus. Furthermore, the finite element simulations were carried out in order to investigate the effects of various parameters on the mechanical behavior of the tubes. The results of the simulation are in good agreement with the experiments. The results show that the section geometry and epoxy adhesives have a significant effect on energy absorption capacity, mean crushing load and maximum crushing load. Investigating both parameters, including section geometry and foam filling, showed that the circular tube has the greatest energy absorption capacity, the mean crushing load and maximum load among all different sections; Furthermore, Epotek-filled tubes have the best performance among the epoxy adhesives-filled ones. On the other hand, circular Hysol-filled tubes have the least energy absorption capacity, mean crushing load and maximum load among tested specimens. It was concluded that circular tubes filled with Epotek adhesives have the most energy absorbing capacity and mean crushing load, whereas circular tubes filled with Hysol-filled ones have the least energy absorbing capacity and mean crushing load.
