An investigation on the response of circular ductile cantilevers subjected to air-blast

A simple analysis of a cantilever subjected to uniform steady flow is outlined. The analysis includes the effect of material strain-rate and strain-hardening on the response. Accompanying this analysis is the result of an experimental investigation on the response of uniform solid circular cantilevers exposed to air-blast loading. The explosion test was conducted at the Woomera Prohibited Area, South Australia. Aluminium cantilever specimens were exposed to a 5t net equivalent TNT charge weight detonation. Details of the analysis and experimental work are presented. Comparison of results suggests that cantilevers could be used as a mechanical indicator to assess air-blast pressure.
