Deformation and fracture of thin ring samples of copper and aluminium by magnetic pulse method

Abstract

Three circuits of loading for copper and aluminium ring samples in the form of thin films by magnetic pulse method are presented. The applicability estimation of electrical circuits made of lumped elements is given. The ways of a significant shortening of the period of time harmonic loading and impulsive loading are shown. The calculation of the electric current change in the ring is made. The piezoelectric transducers for measuring the pulse strain in the rings are developed and applied. The analysis of the experimental results is made.
