EFFECT OF A PULSED ELECTROMAGNETIC FIELD ON STRESS RELAXATION IN CONCENTRATOR-CONTAINING FLAT SPECIMENS

Experimental results of evaluating the pulsed electromagnetic field effect on tensile stress relaxation in specimens with hole a concentrator are presented. The pulsed electromagnetic field is shown to induce local inelastic strain of a metal in the vicinity of the concentrator, which is greatly dependent on pulsed field parameters and concentrator sizes, determining the ratio of thermal-nonthermal current effects.
