Abstract

Models of ultrasonic scattering are useful in the development and validation of ultrasonic testing procedures. In this paper, a numerical model, which can simulate the scattering of ultrasound by a defect orientated normally to the water-sample interface in an immersion test, is described. Compared with other similar work ¹, the new features of this model are (a) that there is no restriction on the size of the defect with respect to the size of the transducer; and (b) that there is no limitation on the position of the defect centre with respect to the central axis of the transducer. The model has been verified by experiment and good agreement was found.
