History effects in the creep of a disordered brittle material
Tero Mäkinen, Jérôme Weiss, David Amitrano +1
We study the creep behavior of a disordered brittle material (concrete) under successive loading steps, using acoustic emission and ultrasonic sensing to track internal damage. The…
Logarithmic vs Andrade's transient creep: the role of elastic stress redistribution
Jerome Weiss, David Amitrano
Creep is defined as time-dependent deformation and rupture processes taking place within a material subjected to a constant applied stress smaller than its athermal, time-independe…
Fluctuations in crystalline plasticity
Jérôme Weiss, Peng Zhang, Oguz Umut Salman +2
Recently acoustic signature of dislocation avalanches in HCP materials was found to be long tailed in size and energy, suggesting critical dynamics. Even more recently, the intermi…
Micro-slips inside a granular shear band as nano-earthquakes
David Houdoux, Axelle Amon, David Marsan +2
We study experimentally the fluctuations of deformation along a shear fault naturally emerging within a compressed frictional granular medium. Using laser interferometry, we show t…
Variety of scaling behaviors in nanocrystalline plasticity
P. Zhang, O. U. Salman, J. Weiss +1
We address the question of why larger, high symmetry crystals are mostly weak, ductile and statistically sub-critical, while smaller crystals with the same symmetry are strong, bri…
Asymmetric damage avalanche shape in quasi-brittle materials and sub-avalanches (aftershocks) clusters
Chi-Cong Vu, Jerome Weiss
Crackling dynamics is characterized by a release of incoming energy through intermittent avalanches. The shape, i.e. the internal temporal structure of these avalanches, gives insi…
