Abstract

Metallic rings made of D16 aluminum alloy are studied upon the application of a distributed radial load by a magnetic pulse technique. Two approaches making it possible to decrease the period of the sin-wave load by seven and fifty times are developed. In addition, they allow one to determine the instant of rupture of the ring from a flash arising at rupture with the help of a photodetector. Simultaneously, the load pulse and a signal from the photodetector are displayed with a digital oscilloscope. It is shown that, when the load pulse shortens, the ductile component of fracture declines and the samples fail in a more brittle manner.
