An Analytical Evaluation of Spall Suppression of Impulsively Loaded Aluminum Panels Based on a One Dimensional Stress Wave Propagation Model.

Abstract

The response of materials to intense impulsive loading is quite complex. For this reason, an approximate analytical method is used based upon a one dimensional elastic shock approach to analyze the effects of a shaped charge against aluminum panels. This method allows concentration on one aspect of spalling by introducing simplifying assumptions into the governing equations of continuum physics. Then with this information, means to suppress the spall can be developed in order to design or modify an armored vehicle configuration to withstand the catastrophic effects of spallation against its crew members. This work provides a broad overview of stress wave effects in aluminum panels that are caused by rapidly applied loading conditions, together with fundamental results involving elastic shock waves. Results are presented that are useful in obtaining a quantitative appreciation of the behavior of the aluminum under short duration loading.
