“…The non-destructive evaluation aims to characterize a defect by the location, shape and size in contrast to the non-destructive testing, which offers information about the presence or absence of a defect. Conducting materials are often evaluated by ultrasonics (Blackshire, 2017), radiography (Alaknanda et al, 2006), thermography (Montinaro et al, 2017), magnetic induction thermography (Ma and Soleimani, 2014), magnetic flux leakage (Layouni et al, 2017) and eddy current testing (Oneida et al, 2017).…”
