Our Weidlinger Applied Science group uses PZFlex to simulate ultrasonic inspections. Ultrasonic damage detection and characterization is commonly used in nondestructive evaluation of composite laminates. The dispersive waves can result in complicated behavior in the presence of complex damage scenarios.
The video above shows the surface velocities of a simulated ultrasonic inspection of both a pristine laminate (left) and a damaged laminate (right), where scattering occurs in the presence of the delamination. By simulating the inspection of a delaminated composite, we can compare the simulated inspection data with real inspection data to characterize the complex damage.
