Abstract:
In this paper, the energy absorption parameters of walls with rectangular cross section are investigated. The ratio of the sides and sides of the diameters are two main parameters for conducting the analysis. Analysis has been done by ABAQUS software and the obtained result indicates that the best values of the energy absorption parameters are 39.88 KN for peak load and sample D; 19.61 KN for mean load crushing and sample A; 1.47 KJ for energy absorption and sample A and 15.05 KJ/Kg for the specific absorbed energy and sample A reported. Also, according to the modeling results, the response surface method was choosing as the selected model. The results of optimization using the genetic algorithm showed an optimal amount of specific energy absorption was equal to 14.51 KJ/Kg, in the ratio of the sides 2 and side’s diameter 0.67 was achieved
