Description
In this talk, I present a summary of studies on the impact of a projectile in dense suspensions, based on published papers that theoretically and experimentally [1-4].
In the first part, I focus on the early-stage dynamics of the impact, which the floating model can describe without consideration of the elastic force acting on a projectile [2,4].
In the second part, I discuss how the elastic force acting on the projectile appears after the impact [2,3].
