Elastic shock response of an air-backed plate to underwater explosion

The shock parameters of the combined charge were determined experimentally. Subsequent experiments on a plate panel were affected by an explosion of the aforementioned combined charge at various standoff distances. The plate panel under the same experimental conditions was numerically analyzed using the package USA/DYNA. The acceleration, velocity and strain histories of the target plate obtained from both experimental tests and numerical analysis were compared. The experimental and numerical results correlate well with each other.
