THE STABILITY OF A CLAMPED SHALLOW ARCH SUBJECTED TO IMPULSIVE LOADING

Abstract

Clamped circular aluminum arches have been explosively loaded using a spray deposited light ignited explosive (Silver Acetylide-Silver Nitrate). Using high speed photography and computerized data reduction, a detailed time history of the arch deflection has been obtained. This deflection was fitted with mode shapes in order to display the motion graphically. The experimental data shows that the clamped arch does not have a jump in response with increasing load level, but a transition from small displacement response to a large displacement response over a sizable range of load level.
