In this paper, we introduce a newly developed semi-analytical model to predict the total focusing method (TFM) amplitude sensitivity map for both nondirectional and directional flaws.

The same leaps in technology that have taken us from Pac-Man to today’s virtual-reality gaming are having a big impact on nondestructive inspection.

Although initially developed as a method for detecting defects in structures in order to safeguard against catastrophic failures, ultrasonic non-destructive testing (NDT) has evolved immensely to a technique considered the mainstay for the NDT industry.
