Abstract
General Yielding Fracture Mechanics Concepts have been used to evaluate and compare thickness effects, J-integral estimation procedures and methods of crack detection in three point bend test pieces of prestrained 316 stainless steel. The results suggest that no thickness effects will exist in irradiated test pieces so long as the failure mode is one of ductile fracture. The choice of toughness parameter, whether fracture initiation be characterised in terms of the contour integral J or Crack Opening Displacement, appears to be relatively unimportant since both criteria appear to predict critical defect sizes of similar magnitude. Suitable crack monitoring procedures have been evaluated for subsequent irradiated tests, and it would appear that a direct current potential drop technique is the most sensitive for a given specimen geometry and toughness level.
