A Simplified Method for Evaluating the Dynamic Response of the Metal Sandwich Structure under Explosion Load

The metal sandwich structure is characterized by light weight, high stiffness, and high-impact energy absorption capacity, which considered a good alternative protective in explosion scenarios. In this paper, four design forms of the are introduced, dynamic response under load researched. Then, new analytical method proposed to predict load, numerical simulations carried out verify accuracy analysis method. designed for aerial explosions without considering fluid–structure interaction. addition, series parameter studies out, including influence face sheet aspect ratio, core height, thickness on load. research paper has reference value anti-explosion will provide useful optimization structure.
