Abstract: This study examined the effect of the upper surface slope and the number of cells in the side beams on the collapse properties using experimental and numerical tests. The numerical studies were conducted with LS-DYNA software, and the accuracy of numerical results was investigated by experimental tests. Using MATLAB software, the second-degree polynomial functions were obtained for the collapse properties of the specimens. Also, after the optimization by the decomposition method, the best mode was introduced for the specimens. The studies on collapse properties showed that increasing the number of cells leads to a decrease in all collapse properties, and increasing the upper surface slope leads to an increase in the collapse properties. Moreover, the optimization results by decomposition method showed that this method could suggest the most optimal model for multi-cell and sloping beams.

Abstract: Thin-walled structures with nested cross-sections have been introduced in recent years as structures with high energy absorption capacity. In this research, a new type of energy absorbers is introduced, which is a combination of two different elements which are subjected to lateral and axial loads simultaneously. The study has been done experimentally and numerically in the numerical part, LS-DYNA software was used for computer simulations. The outer part of the introduced absorbers has square shells with a thickness of two millimeters that absorbs energy under lateral loading. The inner part of new absorbers is a shell with a rectangular cross-section that collapses under axial compression. The obtained results showed that these structures can increase the energy absorption by 36 and 32% of the total energy absorbed through each component separately. In the experimental part, the accuracy of numerical results was checked, and good agreement was observed. In the final part of this research, using Minitab software and based on the response surface method (RSM), the most optimal absorbers in terms of specific energy and maximum force were introduced.
