摘要：The article describes the method of determination of limit velocity for the aluminium alloy sheet metal from the airplane fuselage skin hit by a pistol projectile of calibre 9 mm with utilisation of 2D FEM model of interaction between the projectile and the sheet metal. The simulations are based on accomplished firing experiments and results are compared. The results of simulation can be utilised for prediction of level of damage of aircraft fuselage in case of firing on board of the plane.
