Abstract

An efficient Finite Element procedure for predicting the complete scattering behavior for an arbitrarily-shaped defect which is located near a free surface in an otherwise homogeneous isotropic half-space is presented. The data provided by this model is then used for simulating an ultrasonic array response for different near-surface and surface-breaking defects. Example results for 2D array (3D defects) are presented and compared with the experiment. Its practical application to the volumetric inspections of thin section is discussed. © 2012 American Institute of Physics.
