Numerical Investigation of Excitation of Various Lamb Waves Modes in Thin Plastic Films
Applied Sciences, 2022 Ultrasonic-guided waves are widely used for the non-destructive testing and material characterization of plates and thin films. In the case of thin plastic polyvinyl chloride (PVC), films up to 3.2 MHz with only two Lamb wave modes, antisymmetrical A0 ...
