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…
From plastic flow to brittle fracture: role of microscopic friction in amorphous solids
Kamran Karimi, David Amitrano, Jerome Weiss
Plasticity in soft amorphous materials typically involves collective deformation patterns that emerge upon intense shearing. The microscopic basis of amorphous plasticity has been…
Compressive failure as a critical transition: Experimental evidences and mapping onto the universality class of depinning
Chi-Cong Vu, David Amitrano, Olivier Plé +1
Acoustic emission (AE) measurements performed during the compressive loading of concrete samples with three different microstructures (aggregate sizes and porosity) and four sample…
Damage-cluster distributions and size effect on strength in compressive failure
Lucas Girard, Jerome Weiss, David Amitrano
We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local dama…
Emerging complexity in a simple model of the mechanical behaviour of rocks
David Amitrano
We propose a mechanical model for the behaviour of rocks based on progressive damage at the elementary scale and elastic interaction. It allows us to simulate several experimental…
