Abstract

Abstract

One-dimensional cylindrical load was imposed on the middle part and half height of the metal cylinders which have the initial height of 160 mm, the wall thickness of 4 mm and the external diameter of 48 mm, by the way of an electric exploding wire initiating explosives, and then drove the nylon lining to expand the metal cylinder. At the same time, a validity criterion of the one-dimensional cylindrical load was proposed based on the load or radial velocity monitoring on the outside surface of the cylinder along its axis and circumference. Compared with the load of sliding detonation, the one-dimensional cylindrical load has the advantages of simple stress state and easy analysis as a problem on a simplified two-dimensional axial symmetrical structure, and can provide an explicit analysis on the stress components related to the fracture of the cylinder. Based on the radial velocities of the test points distributed at the outside surface of the cylinder, a method was proposed to diagnose the initial fracture over the periphery of the cylinder. The principle of the proposed diagnosis method is that the fracture of the cylinder under homogeneous load can result in the bifurcation (or change of the evolution trend) in the uniform velocity-curve cluster. And the initial fracture time and position will be the same as the bifurcating time of the velocity curves and the position of bifurcated velocity curve, respectively, when the bifurcation angle of the velocity curves exceeds the normal scope corresponding to structure strength of the tested cylinder. Compared with the high-speed framing photography which can obtain the exact fracture information over part of the periphery of the cylinder, the distributed velocity monitoring can obtain the exact initial fracture information over the whole periphery of the cylinder. The initial fracture parameters of the 304 steel and 45 steel cylinders under one-dimensional dynamic expanding load were obtained by using the established loading and diagnosis technologies for expanding cylinder experiment with linear initiation explosives. These parameters include the fracture strain and the average strain rate. The fracture strain or ductility of the 45 steel cylinder is lower than that of the 304 steel cylinder.
