Jesse J. Sabatini

AbstractThis review article consists of efforts focused on the development of illuminating pyrotechnics. Examined will be the methods of generating red‐, green‐, yellow‐ and blue‐light‐emitting illuminating pyrotechnics. Ways to improve luminosity, spectral purity, and burn rate will be discussed. Recently developed formulations concerning the development of environmentally friendly illuminating pyrotechnics will also be presented.

In this paper, the dynamic deformation and rupture of thin metal plates subject to underwater shock wave loading are studied by using high-speed 3D digital image correlation (3D-DIC). An equivalent device consist of a gas gun and a water anvil tube was used to supplying an exponentially decaying pressure in lieu of explosive detonation which acted on the panel specimen. The thin metal plate is clamped on the end of the shock tube by a flange. The deformation and rupture process of the metal plates subject to underwater shock waves are recorded by two high-speed cameras. The shape, displacement fields and strain fields of the metal plates under dynamic loading are obtained by using VIC-3D digital image correlation software. The strain gauges also were used to monitor the structural response on the selected position for comparison. The DIC data and the strain gauges results show a high level of correlation, and 3D-DIC is proven to be an effective method to measure 3D full-field dynamic response of structures under underwater impact loading. The effects of pre-notches on the failure modes of thin circular plate were also discussed.
