Self-Sensing Nonlinear Ultrasonic Fatigue Crack Detection under Temperature Variation †

Self-Sensing Nonlinear Ultrasonic Fatigue Crack Detection under Temperature Variation †

This paper proposes a self-sensing nonlinear ultrasonic technique for fatigue crack detection under temperature variations. Fatigue cracks are identified from linear (α) and nonlinear (β) ultrasonic parameters recorded by a self-sensing piezoelectric transducer (PZT). The self-sen...
