Abstract

PURPOSE:To permit the observation of the fatigue condition of a specimen by a method in which a driving bar is reciprocally moved to apply a repeated bending stress to a specimen and then electron rays are scanned. CONSTITUTION:The test specimen 3 is laid and fixed between the specimen supporters 5a and 5b and then a testing device is established in the test room 1. Then, when positive and negative voltages are repeatedly applied to the motor 13 from the power source 15, the driving bar 8 is reciprocally moved from side to side to apply a repeated bending stress to the specimen 3. After applying the bending stress desired times to the specimen, the surface of the specimen 3 is scanned by the electron rays EB in order to observe the fatigue condition of the specimen 3 due to the repeated bending stress applied.
