Abstract

An experimental assessment of reproducibility and repeatability of direct tensile strength tests was carried out. Tests were conducted on two rocks (granite, sandstone), in four laboratories located in Canada, Germany, Spain and Sweden. Direct tensile strength test with deformability measurements on cylindrical rock specimens was found operationally feasible. Some shortcomings in current methodologies have been found, such as inappropriate loading rates or no recommendations for deformability measurements. This work provides new insights for potential future improvements of the existing testing methods.
