9 mm Parabellum - Opis:
- This paper presents implementation and validation of a numerical model of the Twaron® CT709 fabric under impact of the 9 mm FMJ Parabellum projectile (with a soft lead core and a hard brass jacket with a velocity of 365 m/s). The fabric model was made with the use of Autodesk Inventor Professional 2012 program, and computer analysis was conducted with using the ANSYS-Autodyn v12.1.0 program. Geometrical model and strength parameters of the fabric were chosen from literature data. For the numerical analysis of soft body armour three variants of boundary conditions for the fabric were adopted. A sample with the dimensions of 50 × 50 mm made of 16 layers of the Twaron® CT709 fabric was used. The simulations for a quarter of the model with two planes of symmetry were performed. The physically correct behaviour of the fabric under the influence of penetration by a projectile was obtained in the numerical simulations and is demonstrated in this paper.
