Experimental evidence of seismic ruptures initiated by aseismic slip

Autor: Yohann Faure, Elsa Bayart

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-11 (2024)

Abstract Seismic faults release the stress accumulated during tectonic movement through rapid ruptures or slow-slip events. The role of slow-slip events is crucial as they impact earthquakes occurrence. However, the mechanisms by which slow-slip affe

The ambition of the RADIOTRANSNET network, launched by the INCa at the end of 2018, is to create a French research consortium dedicated to preclinical radiotherapy to foster scientific and clinical interactions at the interface of radiotherapy and ra

International audience; Contacting bodies subjected to sufficiently large applied shear will undergo frictional sliding. The onset of this motion is mediated by dynamically propagating fronts, akin to earthquakes, that rupture the discrete contacts t

International audience; The onset of sliding motion is conditional on the propagation of rupture fronts that detach the contacting asperities forming a frictional interface. These ruptures, when propagating over a fault surface, are the most common m

Fracture mechanics determine the lengths of interface ruptures that mediate frictional motion

Publikováno v: Nature Physics
Nature Physics, Nature Publishing Group, 2016, 12 (2), pp.166-170. ⟨10.1038/nphys3539⟩

International audience; The transition from static to sliding friction is mediated by rapid interfacial ruptures 1-5 propagating through the solid contacts forming a frictional interface 6. While propagating, these ruptures correspond to true shear c

Critical evaluation of state evolution laws in rate and state friction: Fitting large velocity steps in simulated fault gouge with time‐, slip‐, and stress‐dependent constitutive laws

International audience; The variations in the response of different state evolution laws to large velocity increases can dramatically alter the style of earthquake nucleation in numerical simulations. But most velocity step friction experiments do no

Frictional Resistance within the Wake of Frictional Rupture Fronts

Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2017, 118 (23), ⟨10.1103/physrevlett.118.234301⟩

Frictional resistance to slip, $\ensuremath{\tau}$, is determined by the real area of contact, $A$, and the shear strength of the contacts forming the frictional interface. We perform simultaneous high-speed local measurements of $\ensuremath{\tau}$
