Abstract

Abstract

As polyurethane foam has a good cushioning and energy absorption performance, the sandwich structure with polyurethane foam as core and the steel as the shell plate has been widely used in engineering application. In this paper, in order to study the anti-explosion performance of the sandwich structure, the numerical simulation by Ansys/Autodyn nonlinear finite element code is adopted to analyze the energy absorption properties of the sandwich structure under blast loading and compared with that of the steel plate that has the same area density. The results show that, with the polyurethane foam as core body, the energy sandwich structure absorbed is 1.49 times that of the steel plate with the same area density, and the anti-explosion performance of the overall structure is greatly improved.
