Abstract

Abstract

In the present work we developed a strain wire measurement technique that can be used to measure the dynamic deformation process of cylindrical explosion vessels. The strain wires, compactly fixed along the circumference of the explosion vessels, extended synchronously when the vessels deformed due to the wires' good ductility. Coupled to appropriate circuitry, the resistance profiles of the alloy wires were measured to determine the dynamic deformation process of the explosion vessels. A 120 g TNT spherical high explosive experiment was performed in a cylindrical steel shell. The circumferential deformation curve of the shell was obtained, the peak value of which exceeded by 20%. The result of the strain wires measurement accorded with both the simulation result and the deformation data from the cylindrical steel shell experiment.
