✦ Synopsis

The paper discusses the applicability of the ISRM fracture beam specimen to the testing of interfaces between paste and rock. The method is suitable for interface tests in which rough fractured rock surfaces or prepared rock surfaces are required. Some typical results are presented and discussed in terms of different failure modes. A formula for equivalent elastic modulus of a composite beam is also introduced.
