Crack Closure Stress Crack Depth Microwave Water Environment
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....

Back-Scattering Wave Closed Crack Crack Opening Thermal Stress
This paper presents the ultrasonic response for closed crack under thermal loading. A part of stainless steel plate with a tightly closed crack is cooled for three minutes, and the therm al stress for reducing the crack closure stress is generated in the plate specimen. The back -scattering wave from the crack surface is monitored for several hours after cooling started....
