Fatigue damage evaluation of metallic components based on the maximum Lyapunov exponent of modified Duffing system
Because the Duffing equation is very sensitive to weak signals and noise immunity, the modified Duffing detection system is applied to detect the weak nonlinear signal in nonlinear ultrasonic experiment. Firstly, the Duffing equation is improved to construct detection models to detect the nonlinear...
