Plastic response of a 2d amorphous solid to quasi-static shear: Ii-dynamical noise and avalanches in a mean field model
A Lemaître, C Caroli - arXiv preprint arXiv:0705.3122, 2007 - arxiv.org
We build a minimal, mean-field, model of plasticity of amorphous solids, based upon a
phenomenology of dissipative events derived, in a preceding paper [A. Lemaitre, C. Caroli …
