Mechanical data from laboratory shear failure experiments of fluid saturated Westerly granite (NERC Grant NE/S000852/1)
Data recorded during triaxial rock deformation experiments of Westerly granite in the presence of pressurised pore fluids (water). Data consists of mechanical data (load, displacement, confining pressure) and pore pressure data (up- and downstream pore pressure, upstream intensifier volume, four pore pressure transducers mounted on sample). Contains all data necessary to evaluate the results presented in the paper entitled: 'Dilatancy stabilises shear failure in rock' by Aben and Brantut, submitted to Earth and Planetary Science letters, and available at arXiv (arXiv:2101.10036).

Data Quality
Data was collected on a triaxial deformation apparatus at the Department of Earth Sciences (UCL). The triaxial deformation apparatus was equipped with an axial load cell and displacement LVDT, and confining pressure was applied through silicone oil and monitored with a pressure transducer. The sample assembly in the triaxial apparatus was equipped with electrical lead-throughs to which were connected the pore pressure sensors. The apparatus was used in conjunction with an external pore pressure intensifier which monitored both pore volume and pore pressure. All data measured by the sensors were recorded with a LabView program on a single PC. Data was further analysed using scripts written in Julia coding language.
