This paper investigates and demonstrates the nondestructive capability of ultrasonic waves and magnetic Barkhausen noise (MBN) in stress evaluation of Q345 plates. A 10mm thick Q345 specimen was subject to a concentrated load by a stressing jack, known as three-point bending test. A finite element m...
