Abstract
The present invention relates to a material strength measuring apparatus for specimens having a curved surface or an irregular surface with high accuracy. The measuring apparatus according to the present invention comprises: a supporting stand (1) for fixing a specimen (19) thereon; a guide member (3) fixed on the supporting stand so as to be vertical with respect to the supporting stand; a moving member (26) moving linearly and vertically with respect to a measured surface of the specimen along the guide member; a rotating blade (10) urged toward the measured surface of the specimen; a rotating blade supporting body (8) moving with the moving member linearly and vertically with respect to the measured surface of the specimen; a blade rotating motor (6) fixed to an end of the rotating blade supporting body; elements for forcing the rotating blade into the surface of the specimen; a torque detector (5) for detecting cutting resistance against the rotating blade; a vertical displacement detector (7) fixed to the moving member for detecting vertical displacement of the rotating blade; and a recorder (25) for recording outputs of the torque detector and the vertical displacement detector.
