Modeling of Ultrasonic Nonlinearities for Debris Cloud-Induced Micro-Voids Characterization: Theoretical Analysis and Numerical Validation

Modally selective nonlinear ultrasonic waves for characterization of pitting damage in whipple shields of spacecraft

“…However, the HVI induced-pitting damage will cause variations in the elastic constants of materials, such as the mass density and the elastic modulus, leading to the dispersion curves remain unclear. The effective Young's modulus p E and Poisson's ratio p µ of the plate-like waveguide undergo pitting damage can be defined as 20 , 2…”
