Abstract
Many analytical studies have been performed on the impact resistance of structures such as rock sheds subjected to impact loads. However, the phenomena such as penetration of a collision object are essentially difficult to calculate by FEM. This study performed a fundamental review on the application of SPH for analyzing the impact response of structures aiming to establish an analytical method for the elastic-plastic behavior of protective structures. In this study, first, the modeling issues of SPH were considered. In addition, when performing elastic-plastic impact analysis, the means of ensuring analysis accuracy by using the SPH method was reviewed. Finally, a simulation analysis was performed for the weight-drop test of RC beam conducted and possible application of the SPH method was verified.
