2011:16 Modelling of ultrasonic testing of cracks in cladding
During the last two decades, SSM has supported research to develop a model for the non-destructive test situation based on ultrasonic technique. Such a model is important in many ways, for example to supplement ... are often equipped with a cladding material to prevent material degradation by the influence of media on the surface. This cladding material, often anisotropic, makes the ultrasonic examination more difficult...
