Research on the acceleration phenomenon of projectile leaving the target when penetrating thick concrete target
International Journal of Impact Engineering(2022)
Abstract
•There is a short-term acceleration phase in the process of penetrating a thick concrete target.•The deceleration overload is reversed, that is, the deceleration sign changes.•The friction between the projectile and the target is converted into heat and further into the bottom thrust of the projectile.•The calculation method of the acceleration peak in the acceleration phase is given.
