Abstract

The dynamic plastic response of structures under blast loading and underwater explosion has found important applications in the design of energy-absorbing and collision protection devices. This paper presents the results of analytical and experimental studies on the response of steel and aluminium circular plates in two different media of air and water. Results of experimental observation of fully clamped plates have been presented. The results obtained are compared with existing empirical relations, a theoretical procedure, and a modified relation offered by Wierzbicki and Symonds. Comparing the experimental and theoretical results, it was observed that considering strain rate effect in the theoretical procedure is essential in obtaining a more accurate prediction of the deflection of the plate. The reasonable agreement between experimental results and relations proves the validity of the proposed predictions, especially when strain rate effect is considered. Since, in the case of air-blast-loaded plates, the deviation from experimental results was noticeable, a new relation for dynamic plastic response of circular plates is suggested, which is based on Zhao damage number. Furthermore, the effect of material and medium is investigated.
