  1. Prediction of the remaining velocity of some handgun bullets perforating thin metal sheets.

    Article - En anglais

    This paper discusses a semi-empirical method, based on the simple Lambert and Jonas (LJ) formula to predict the remaining velocity of a bullet perforating a thin metal sheet.

    This paper focuses on ordinary FMJRN'FMJTC2 and LRN3 pistol and revolver bullets, which generally deform at impact and considers'thin'steel targets (h/d0<0.2) which frequently occur in forensic case work.

    The original parameters of the LJ-formula are substituted by parameters of the target, the perforator and four non-dimensional fitting parameters which were determined by the method of non-linear regression, applying experimental data.

    It was found that the number of necessary model parameters could be reduced to only two for the angular impact of FMJ and three for LRN bullets.
