Ultrasonic Measurement of Residual Stress and Microstructure: From LCR Acoustoelasticity to Phased Arrays, Robotics and Digital Twins
Residual stress influences dimensional stability, fatigue, fracture and structural integrity in welded and additively manufactured components. Ultrasonic methods offer a non-destructive and deployable alternative to diffraction and strain-relief techniques because stress changes elastic-wave velocity through acoustoela...
