| Abstract Scope |
Most of metals failure happens because of the fatigue process which occurs in a metal that is subjected to cyclic loading over time. Early fatigue damage detection based on non-destructive testing (NDT), aids in strategizing necessary treatments, ensuring sustained performance, extended lifespan, and increased durability. This approach fosters sustainability and supports a circular economy. NDT techniques enable the detection of fatigue damage without the destruction of specimen. Techniques such as electrical resistivity and nonlinear ultrasonic testing are employed to detect these fatigue defects. The preliminary findings indicate that both electrical resistivity and nonlinear ultrasonic testing proficiently detect early-stage fatigue defects in metals. These methods reveal significant changes in three distinct regions prior to 20% of the component's fatigue life. |
