摘 要:利用四点弯剪切法研究了岩石纯剪载荷作用下的断裂规律,并提出了岩石发生真Ⅱ型断裂的条件,探讨了测定岩石真Ⅱ型断裂韧性的方法。
Abstract: With the four point bend shear specimens,the fracture behavior under pure shear loading condi-dons was studied and the condition for pure mode Ⅱ fracture to happen was investigated. Furthermore,the mea-surement of determining pure mode Ⅱ fracture toughness was investigated too.
