• 2006:25 Modelling of ultrasonic nondestructive testing of cracks in claddings

  01 januari 2006

  concerned with the modelling of defects in claddings. A cladding is a layer of material that is put on for corrosion protection, in the nuclear power industry this layer is often an austenitic steel that ... between the cladding and the base material is often corrugated.
