A dynamical high velocity pressure on powder is easily produces higher pressure than that of statical pressure. Furthermore, it has the verture of producing homogenized compressed powder, as the transverse direction pressure is small as compared with the longitudinal pressure, and also minimizing the friction force between powder and die wall than in the case of the longitudinal direction pressure. This paper discusses some experimental and simplified theory on a process of a direct impact of a bullet to powder in the die. In this experiment the powder is assumed to be a homogenized material which is composed of powder particle and air. As consider the shock wave propagation throgh the powder under impulsive contact of bullet on it(¹) this consideration requred to treat the problem physically, such as the application of the theory involves the law of conservation of mass. momentam, and together with the stipulation of statecally pressure an appropriate equation of state relating Pressure P. and density ρ(²). and neglected friction force, viscosity and elastic restoration, insertion of both which is strain gauge mounted on steel rods discussed later is measured chainging stress curve on the oscillo scope as time interval has verified experimentally over a wide range of impact parameters for shock wave velocity history.
