Effect of Die Angle on Electromagnetic Riveting Interference

Abstract

By establishing an axisymmetric finite element model of the electromagnetic riveting (EMR) joint, we studied the influence of riveting die angle on joint interference and the driven head. It was found that a decrease in the die angle leads to a decrease in the highest temprature in the adiabatic shearing band (ASB). An increase in interference and contact pressure between the rivet shank and apertue wall was also obeserved when decreasing the die angle, which has been proved to be benificial to the fatigue performance of the joint.
