The quality of these images is good and provides an excellent method of near surface flaw detection. However, certain quantitative aspects of the critical angle phenomenon remain unresolved, making detailed image interpr

This harmfulness will be deduced from a comparison of the actual dimensions of the defect to the critical length ac for that defect, corresponding to the fracture of the sample under a known stress field σ. .
