Very short pulse duration, high pressure shock initiation experiments using electrically driven plastic flyer plates were performed on the explosives LX-10 (95% HMX, 5% Viton binder by weight) and LX-16 (96% PETN, 4% FPC 461 binder by weight) to measure threshold flyer velocities for detonation initiation. For LX-16, threshold velocities were determined for various flyer materials, thicknesses and diameters. This data was calculated using the Ignition and Growth reactive flow model parameters
