摘 要:作者对采用双扭方法测定岩石断裂韧度K10进行了研究,结果表明,此法不仅可行而且可以避免其它方法在测裂纹长度、预裂方式及塑性修正等方面的复杂考虑和繁琐计算,是一种很有发展前途的测定方法。
Abstract: In this paper author has investigated the measurement of rock fracturetoughness K10 by using the double torsion method.The result shows that thismethod is not only feasible but also able to avoid the complexity and thebothersome computation in measuring the crack length,precracking and plasticcorrection by mean of other conventional methods.So it would be a verypromising method.
