چکیده انگلیسی
In this study, the behavior of multi-frusta configurations under axial loading was analyzed, the effect of column spacing, number of tubes, shells, and cone combinations investigated, and multi-objective optimization applied to obtain optimal multi-frusta configurations. The results obtained indicate that the interaction between multi-frusta configurations without shell improves the system's specific energy absorption (SEA), the SEA of multi-frusta tubes can be improved by the rigid outer shell, and the overall energy absorption of restricted size structures benefit from having an appropriate number of multi-frusta configurations. They also show that cross-arranged tapers offer better energy absorption characteristics than other arrangements.
