On Microwave Dual Frequency Technique for Evaluation of Surface Cracks

Abstract:

Article Preview

A method to estimate crack closure stress on the crack surface was introduced. The crack closure stress was estimated based on the compliance technique, while crack depth was measured by means of the microwave dual frequency technique. The effect of crack closure stress on detection and evaluation of a closed crack in a carbon steel by using the microwave dual frequency technique was discussed in details.
