Abstract

One of the main objectives of impact mechanics is the design of a structure resistant to explosion by introducing a structure with a special design pattern while maintaining its lightweight conditions. In this study, the Plastic Deformation and failure pattern of quadrangular metallic plates under localized Impulsive Loading were investigated due to the lack of experimental, analytical, and numerical results in the field of deformation of multilayer structures under Impulsive Loading. In this series of experiments, 26 double-layered metallic plates with different layering arrangements of steel-steel and steel-aluminum in different thicknesses were fabricated and designed. To apply the localized impulsive load, a ballistic pendulum system was used without using standoff distance blast tubes. A thick layer of polyester foam was used to prevent explosive debris. Steel plates in different thicknesses of 1, 2, and 2. 5mm, and aluminum plates in different thicknesses of 1 and 2mm in 5 different layering configurations were used. In the experimental study, parameters such as impulse, central permanent deflection, and longitudinal strains in x and y directions were measured. The results showed that the use of aluminum plate as a backing layer reduces the explosive performance of the double-layered mixed configurations of steel-aluminum plates under localized Impulsive Loading.
