Nonlinear Ultrasonic Testing

Nonlinear Ultrasonic Testing (NLUT) is a technique used to detect changes or damage in materials by sending high-frequency sound waves through them. Unlike traditional methods that measure how much sound is reflected back, NLUT examines how the waves distort or generate new frequencies as they travel. These changes can reveal tiny flaws, cracks, or material fatigue that might not be visible otherwise. By analyzing these nonlinear effects, NLUT provides a sensitive way to assess the integrity of structures and materials, helping identify issues before they become serious problems.
