Dilatancy stabilises shear failure in rock
Franciscus M. Aben, Nicolas Brantut
Failure and fault slip in crystalline rocks is associated with dilation. When pore fluids are present and drainage is insufficient, dilation leads to pore pressure drops, which in…

Off-fault damage characterisation during and after experimental quasi-static and dynamic rupture in crustal rock from laboratory P-wave tomography and microstructures
Franciscus M. Aben, Nicolas Brantut, Thomas M. Mitchell
Elastic strain energy released during shear failure in rock is partially spent as fracture energy to propagate the rupture further. is dissipated within the rupture tip pro…

Fluid pressure heterogeneity during fluid flow in rocks: New laboratory measurement device and method
Nicolas Brantut, Franciscus M. Aben
We present a new type of transducer capable of measuring local pore fluid pressure in jacketed rock samples under elevated confining pressure conditions. The transducers are passiv…
