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…
Micromechanics of high pressure compaction in granular quartz aggregates
Suzanne J. T. Hangx, Nicolas Brantut
The mechanical behaviour of porous sandstones is generally modelled using concepts from granular mechanics, often overlooking the effect of cementation. To probe the key difference…
Insight into the microphysics of antigorite deformation from spherical nanoindentation
Lars N. Hansen, Emmanuel C. David, Nicolas Brantut +1
The mechanical behavior of antigorite strongly influences the strength and deformation of the subduction interface. Although there is microstructural evidence elucidating the natur…
Stability of pulse-like earthquake ruptures
Nicolas Brantut, Dmitry I. Garagash, Hiroyuki Noda
Pulse-like ruptures arise spontaneously in many elastodynamic rupture simulations and seem to be the dominant rupture mode along crustal faults. Pulse-like ruptures propagating und…
