Stress corrosion cracking (SCC) has been shown to cause catastrophic failure of structures. In the case of spent nuclear canisters, radioactive materials may leak through the cracks if they penetrate the tank wall. This work explores the adoption of ultrasonic waves for the purpose of crack detection in thick stainless-steel plates, first by Piezoelectric Transducer (PZT) and then pulsed laser (PL) actuation for a fully non-contact system.
