Webb1 mars 2002 · However, only the model with p=2 can be justified by assuming a constant energy absorbed by a target (Recht and Ipson, 1963). This model can be written as (2) v ̂ res = a ̂ (v imp 2 − v ̂ bl 2 ) 1/2 , v imp > v ̂ bl , a ̂ =M/(M+m) where v ̂ res and v ̂ bl are the impact and the ballistic limit velocities, respectively; M is mass of a blunt impactor, m is … Webbdimensional Recht-Ipson parameter, a, has a value of 0.86 which is identical to the value reported in Table 2. This correspondence is likely due to some serendipity, and the close correspondence of the Recht-Ipson analysis to the present experiments.

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.
