Experimental investigation of an elastic cylinder entering water at high velocity

With reference to the end-on penetration of a cylinder, an attempt is made to deal with the water entry problem as a whole and present a picture of the various processes involved and their interrelationships. The penetration process is considered from the moment of initial contact of the cylinder with the surface of the fluid to transition to the quasisteady regime.Based on a paper read at the Seventh Congress on Theoretical and Applied Mechanics, Moscow, August 1991.
