A model of 2D SH ultrasonic nondestructive testing for interior strip-like cracks near a non-planar back surface in a thick-walled component is presented. The wave scattering problem is solved using a combination of the boundary element method (BEM) and an analytical hypersingular integral equation technique. The model takes into account the action of the ultrasonic transmitter and receiver, and a few numerical examples illustrating the influence of the non-planar back surface are given.
