“…For this study the imaging of a 1 mm diameter circular side-drilled hole (SDH) at a position (0, 20 mm) using the ultrasonic array detailed in Table 2 was investigated. The LL S-matrix for a 1 mm diameter SDH was computed by the separation of variables method [19].…”

Abstract. In this paper, a methodology of using finite element (FE) model to validate a ray-based model in the simulation of full matrix capture (FMC) ultrasonic array data set is proposed. The overall aim is to separate signal contributions from different interactions in FE results for easier comparing each individual component in the ray-based model results. This is achieved by combining the results from multiple FE models of the system of interest that include progressively more geometrical features while preserving the same mesh structure. It is shown that the proposed techniques allow the interactions from a large number of different ray-paths to be isolated in FE results and compared directly to the results from a ray-based forward model.
