RISUltrasonic Guided Wave Scattering Spectra by Hybrid Global–Local Modeling for Nondestructive Evaluation in Composites With Varying Defect Features
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nondestructive characterization and monitoring of defects in composite structures by ultrasonic guided waves are hindered by the complexity of the interaction. Efficient computational modeling of propagating ultrasonic ...
Passive Extraction of Dynamic Transfer Function From Arbitrary Ambient Excitations: Application to High-Speed Rail Inspection From Wheel-Generated Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The general topic of this paper is the passive reconstruction of an acoustic transfer function from an unknown, generally nonstationary excitation. As recently shown in a study of building response to ground shaking, the ...
