Abstract

Composite materials present many challenges for the NDE community. Addressed here is the phenomenon of ray bending due to the introduction of curvature into anisotropic materials, using Dijsktra's algorithm for tracing rays. The influence of several important parameters is identified, and Dijkstra's algorithm is applied to calculating TFM focal laws in both simulated and experimental data. In both cases, an improvement in image quality is observed.
