In many industries, structures are designed to demonstrate good stability against various loadings. Consequently, studying the energy absorption capacity of such structures is of great importance. This paper investigates the energy absorption capabilities of thin-walled hexagonal structures. Experimental tests and modeling were performed on both simple hexagonal structures and improved hexagonal structures. Additionally, the effect of a smaller hexagon inside these structures was studied. The results indicate that increasing the wall thickness in both simple and improved structures enhances their energy absorption capabilities. The specific energy absorption capacity of the simple structure with a thickness of 2.81 mm is 18.79 kJ/kg, representing a 53.76% increase compared to a thickness of 0.3 mm. The improved structure also exhibited higher energy absorption capabilities than the simple structure. The energy absorption value for the simple structure with a thickness of 0.3 mm was 1128 J, whereas it was 2139 J for the improved structure, showing a 62.89% increase. This increasing trend was also observed in both simple and improved structures for the average collapse load. The results of this research provide new insights for the design of improved energy absorbers.
