Abstract
A time-domain boundary element method and an electro-mechanical recipr ocity relation are applied to model the ultrasonic pulse echo in a sol id. Three different coupling boundary integral equations have been obt ained respectively for the scatterer represented by void, liquid and s olid. An exact model is presented for the ultrasonic transmission, sca ttering and reception. (C) 1997 Elsevier Science B.V.
