The applicability of Full Matrix Capture (FMC) and Total Focusing Method (TFM) has been examined for ultrasonic non-destructive inspection for components that have non-planar surfaces. In this work, side drilled holes and EDM notches in a metal test piece that has non-planar surfaces both on the front and back sides were inspected using longitudinal waves, shear waves and their mode converted waves in immersion mode, where the incident point along the surface profile of the test piece was found by using minimum time-of-flight algorithm based on Fermat’s principle.
