Abstract
This work presents a non-destructive method for quantitative essessment of fatigue damage of materials with linear elastic properties using nonlinear ultrasonic techniques. A nonlinear study was conducted on these materials with fatigue and shot peening processing using a nonlinear ultrasonic technique. A numerical method based on the semi-analytical finite element (SAFE) technique, was used to obtain the phase-matching modes of the specimens. Experiments confirm that the nonlinearity for shot peening and samples with a certain level of fatigue shows a tendency to increase with levels of fatigue.
