摘要
作者对采用双扭方法测定岩石断裂韧度K_(10)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。
In this paper author has investigated the measurement of rock fracture
toughness K_(10) by using the double torsion method.The result shows that this
method is not only feasible but also able to avoid the complexity and the
bothersome computation in measuring the crack length,precracking and plastic
correction by mean of other conventional methods.So it would be a very
promising method.
