Shock interaction is a research area that focuses on the complex interactions between shock waves in various environments. This field investigates how shock waves interact with each other, with solid or fluid structures, or with the surrounding medium. The study of shock interaction is important in understanding the behavior of shock waves in different situations, such as in supersonic flows, explosions, or impact dynamics. Researchers in this field use experimental, computational, and theoretical methods to study shock interactions and their effects on materials and structures. The findings from this research area have applications in aerospace engineering, defense, and material science.
