概要
Quantitative evaluation of small cracks in stainless steel under water which was use to simulate the environment of u nclear reactor was demonstrated. The crack depth was evaluated by the means of the microwave dual frequency technique , and the crack closure stress was estimated based on the compliance technique. The cracks were detected significant ly with larger closure stress and the effect of the closure stress to the evaluation of crack depth was investigated.
