Experimental Investigation of the Rapid Loading of Clamped Circular Plates by an Electrical Discharge in Water.
Abstract
A high voltage, high current electrical discharge is used to produce a shock wave in water which is then reflected from a plate in order to produce rapid loading of the plate. Discharge energies of 1400 to 2800 joules are used to load 6 inch diameter polycarbonate (Lexan) clamped circular plates. The center deflection of the plate is measured as a function of time by using a touch wire technique. Large dynamic deflection but very little permanent deformation is observed and the results do not correlate very well with existing models of rigid/plastic deformation. This is attributed to non-linear and very highly time-dependent material properties. In addition, some estimates on the amount of energy transferred from the discharge to the plate and a discussion of scaling of the experiment are given. (Author)
