Webb17 jan. 2024 · To predict the ballistic limit of the projectile, the Recht–Ipson model can be used. Equation ( 2) shows the required relation of Recht–Ipson model [ 12 ]. Later in the advancement of ballistic limit prediction, Eq. ( 2) was modified by Lambert and Jonas, by assuming constant energy transferred to the plate and proposed Eq. ( 3 ). WebbSome phenomenological and semi-phe- nomenological models describing penetration phenomenon that imply Eq. (1) were suggested in Ben-Dor et al. (1998, 2001). However, only the model with p ¼ 2 can be justiﬁed by assuming a constant energy absorbed by a target (Recht and Ipson, 1963). mick christopher
