Description

Numerical studies of realistic ultrasonic NDT situations in their most general form assume arbitrarily shaped defects excited by pulsed transducer waves all subject to the specimen’s external boundaries. The combination of three features, transmitter model, ultrasound/defect interaction, and receiver model makes a thorough quantitative evaluation extremely difficult, Although a numerical finite element code capable of handling ultrasonic wave propagation and scattering has been developed [1,2] the overall system remains incomplete without apropriate transducer models.
