IMPACT CRUISING STRENGTH OF ICE

Testing techniques and experimental data acquired by many authors are examined. The impact crushing strength of ice can be defined via the specific impact crushing energy which is the impact crushing energy related to the volume of the crushed ice. This definition is used in conjunction with a mathematical model of ice/rigid body impact to describe ice impact crushing strength and various impact characteristics introduced by other authors are established. The available experimental data gives approximate estimates for the magnitudes and variation range of the impact crushing strength for various types of ice and conditions, as well as for the effects of ice temperature, impact velocity and indenter's mass and shape. More studies are necessary to substantiate and quantify these preliminary conclusions.
