Plate Response Analysis Using Shock Tube

Abstract

Rectangular aluminum plates, 0.508 and 0.813 mm thick, were subjected to increasingly higher levels of reflected shock pressures, ranging from 77 to 339 kPa, at the closed-off end of a shock tube. The resulting large transient deflections of the plates were measured optically and compared with counterpart finite difference code calculations. The incorporation of a simple 'piston theory' model in the code to account for the fluid-plate interaction was found to improve correlation with test results. Keywords: Thin plates; Large dynamic response; Elastic-plastic analysis; Fluid-structure interaction; Piston theory; Reflected shock wave loadings; Finite difference analysis; Correlation of displacement histories.
