Impact propagation study on composite plates

Abstract

Much research has already been done in the field of rapid dynamics, particularly with regard to impact stress, which remains of great importance. However, these challenges are compounded when it comes to studying composite materials, particularly with regard to their homogenization and characterization. With this in mind, our current study focuses on the analysis of the impact and propagation of the shock wave through plates made of composite materials, whether they are sandwich structures or laminated plates. We used a 16 mm diameter impactor with falling weight in our experiments. We also conducted vibration characterization tests, which allowed us to collect additional data essential for our different applications. The results obtained have been processed in such a way as to make them easily accessible and exploitable.
