PROBLEM TO BE SOLVED: To realize a sacrifice test piece which is simple with a higher sensitivity and moreover, allows the expectations of various advantages such as broader applicable range.;SOLUTION: In the sacrifice test piece artificially torn across the width at the central part in the longitudinal direction of the body thereof, the plate surface of the body is cut off along the direction of the extensions of the artificial tearing to form a very thin part. In the process, the plate surface of the body is worked to make a circular arc-shaped groove or to make a V groove thereby forming the very thin part. The thickness of the very thin part is selected to be about 0.1 mm.;COPYRIGHT: (C)2002,JPO
