摘要
为了验证作者最近关于流变断裂理论而提出的变质量断裂模型,本文提出了一种新的光测裂纹扩展速度和形状的新方法,经实际测量表明该方法有简便、精确、实用等特点,是一种较为理想的断裂力学实验新方法。
In order to demonstrate the correctness of the theory of Variable-Mass Fracture Modelproposed by authors in recent research on rheological fracture theory, a new opticalsurveying procedure to measure the propagation velocity and shape of crack was presen-ted and using this method has performed practical determination. The experimentalresults showed that this method is simple, convenient, practical and accurate.
