Hysteresis loop as the indicator of residual stress in drawn wires

Abstract

The paper investigates the possibility of using the magnetic method for non-destructive determination of residual stress in drawn wires. The change in residual stress for different processing speeds is reflected in the shape of hysteresis loop. A simple model for stress-dependent hysteresis, based on the concept of the effective field, is proposed. The effective field includes an additional term related to stress, in accordance with previous Jiles’ and Sablik's results. The presented description may be useful for technologists seeking a simple tool for predicting residual stress.
