Dominant mode of planar fractures and the role of material properties

This study is aimed at determining the regions where different planar fracture modes would prevail in the kα-kc-f space, in which the loading is characterized by the loading ratio kα=KI/KII, while the material properties are characterized by the fracture toughness ratio kc=KIC/KIIC and the coefficient of friction of the material f. The mode of fracture is determined from the stress state on the fracture plane, which is distinguished from the...
