Abstract

Abstract

An electric probe measurement technique was proposed to measure the deformation undergone by the ektexines of the cylindrical steel shells subjected to the detonation of spherical explosive charges inside them.Numerical simulation was carried out to forecast the deformation of the steel shell ektexine at the section of the explosion center in the case of the spherical high-explosive charge equivalent to 120g TNT as well as 180g TNT.Based on the above, the corresponding experiments were conducted.The radical displacements at the different times were obtained at the characteristic points for the ektexines of the cylindrical steel shells.The measured results by electric probes are consistent with the deformation of the cylindrical steel shell after the experiments.
