Comparision of Perforation Theories and Some Experimental Results


Mechanical Engineering, Tarbiat Modarres University


In this paper it is shown that the variety of mathematical models proposed, such as Nishiwaki [1], Recht and Ipson [2], Lambert and Jonas [3], Awerbuch and Bodrer [4], Nixdorf [5] and the modified analysis given by the author in earlier papers [6,7] almost all adhere to one basic form This shows clearly the relationship between the striking velocity WI, the residual velocity Wf, and the ballistic limit velocity WB It is also shown that in the case of modified analysis [6,7] Equation (1) may be easily applied to the preformation of double and multilayer targets. The computed results also shown a good correlation with experiments.
