Research on the Residual Stresses in Cold-Formed Hat-Shaped Section

Abstract:

In the paper,the electrical discharge machining(EDM) technique was used to cut strips for cold-formed residual stress measurement of hat-shaped section.After adjusting the electrolyte ratio,designing specific the cutting tool and improving the methodof antiseptic treatment,the test results improved significantly. Electrical resistance strain gauges with EDM cutting technique were used to establish the magnitude and distribution of the residual stresses in cold-formed hat-shaped section.Based on the experimental findings, an idealized distribution pattern of the residual stress in cold-formed hat-shaped section is presented.
