金属延性断裂韧性的测量精度主要取决于裂纹扩展量的测量精度。本文提出了一种新的测量方法照相放大法,该方法能够真实反应试样裂纹扩展实际情况。
The measurement accuracy of ductile fracture toughness mainly depends on the measurement accuracy of crack propagation. In this paper, a new measurement method photometric amplification method is proposed, which can reflect the actual situation of crack propagation.
