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.
Key words: shear fracture form fracture toughness
