This paper addresses three-dimensional dynamic finite element analysis and validations for strain-rate dependent elastic-plastic sandwich steel plate with various corrugated core arrangements subjected to dynamic air pressure loads. The sandwich steel plate consists of top and bottom flat substrates of Steel 1018 and corrugated core layers of Steel 1008. The developed model is validated with a set of shock tube experiments. Various corrugated core arrangements are taken into consideration for optimizing core design parameters in order to maximize mitigation of blast load effects onto the structure.
