| Abstract: | 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. |
