Nonlinear Ultrasound Crack Detection with Multi-Frequency Excitation—A Comparison
Nonlinear ultrasound crack detection methods are used as modern, non-destructive testing tools for inspecting early damages in various materials. Nonlinear ultrasonic wave modulation, where typically two or more frequencies are excited, was demonstrated to be a robust method for failure indicators w...
