Abstract :
The magnetic properties of material are sensitive to applied stress. The aim of this paper is to designed and fabricated a hysteresis imaging apparatus for nondestructive evaluation of stress concentration in ferromagnetic material. It has been applied successfully to measure the hysteresis loops of Q235 steel under various fixed compressive stress. The remanence Br derived from the loops is more accurate and suitable to characterize the stress in a material.
