Abstract
In this study, in order to investigate dynamic behavior of a newly developed absorbing system by means of Geocell filled with one-size aggregate, 3D-FE impact response analysis of the Geocell walls was carried out taking impact velocity of the weight as variable. The applicability of the proposed method was investigated comparing with the experimental results. From this study, the following results were obtained: (1) the time histories of the impact force, penetration of the weight and transmitted impact stress obtained from FE analysis were almost similar to those of the experimental results; and (2) the envelope of transmitted impact stress and the deformation of Geocell wall can be appropriately simulated by means of the proposed numerical analysis method.
