A Sideways Crack-Path Instability Amplified by Slow Loading
G. Pallares, O. Ramos, L. Vanel
Crack-path instabilities in solids are typically associated with high propagation velocities. In contrast, we show that nanoparticle-filled elastomers exhibit a sideways crack-path…
Avalanches can increase stored energy in a granular fault
A. Douin, E. Saurety, V. Levy dit Vehel +4
Slowly sheared granular materials generally store mechanical energy and dilate between abrupt failures that release energy and compact the material. Here, simultaneous measurements…
Continuously sheared granular matter reproduces in detail seismicity laws
S. Lherminier, R. Planet, V. Levy dit Vehel +4
We introduce a shear experiment that quantitatively reproduces the main laws of seismicity. By continuously and slowly shearing a compressed monolayer of disks in a ring-like geome…
Sound and light from fractures in scintillators
A. Tantot, S. Santucci, O. Ramos +7
Prompted by intriguing events observed in certain particle-physics searches for rare events, we study light and acoustic emission simultaneously in some inorganic scintillators sub…
Experimental study of the effect of disorder on subcritical crack growth dynamics
Osvanny Ramos, Pierre-Philippe Cortet, Sergio Ciliberto +1
The growth dynamics of a single crack in a heterogeneous material under subcritical loading is an intermittent process; and many features of this dynamics have been shown to agree…
Softening induced instability of a stretched cohesive granular layer
Hector Alarcon, Osvanny Ramos, Loïc Vanel +3
We report on a cellular pattern which spontaneously forms at the surface of a thin layer of a cohesive granular material submitted to in-plane stretching. We present a simple model…
