DOP Test Evaluation of the Ballistic Performance of Armor Ceramics against Long Rod Penetration.

A series of DOP tests with lateral confinement have been carried out and a linear relation between the residual penetration in RHA and the alumina thickness has been obtained. The rod configuration and the initial transient impact are the two factors that cause the gradual decrease of the differential efficiency factor (DEF) when the ceramic thickness is increased in literature. A new improved DEF definition is proposed to characterize the thick tile ceramic ballistic performance based on a more physical analysis. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
