A New Method to Estimate the Projection Angles of Fragments from a D Shape Configuration

Abstract:

The oblique shock wave theory is used to describe the process of detonation wave shocking on the metal surface. And after the transmission wave in metal transmitted to the free surface of metal, the velocity multiplication law of free surface is used to simplify the shock wave theory to estimate the velocity of particles in metal. Then the projection angle is obtained from the velocity direction to the normal of initial metal surface. In addition, the explosion experiments of a D shape configuration have been done to validate this method. And the results show that this method is in better agreement with experimental projection angles than traditional Taylor equation.
