Paper presented at the ISRM European Rock Mechanics Symposium - EUROCK 2017, June 20–22, 2017
Paper Number: ISRM-EUROCK-2017-113
... Abstract It is essential to understand the mode I fracture toughness of rock under in situ conditions found underground, such as confining pressure, for assessment of the stability of underground rock structures. Some researchers have performed several types of fracture toughness tests...

... role in brittle fracturing. The Cracked Chevron-Notched Brazilian Disc (CCNBD) samples were tested to determine the fracture toughness of monsonite and sandstone samples. Since conducting fracture toughness tests are quite hard compared with the Brazilian test, the tensile strength can be determined...

... This study presents a newly suggested test method called "Punch through Shear Test" which was originally proposed by Backers and Stephansson. The purpose of this study is to check the validity of the suggested test method by performing Mode II fracture toughness test for Daejeon granite...
