COST exploratory workshop on
Physics of Amorphous Solids: Mechanical Properties and Plasticity in Les Houches, from Sunday, 14 to Friday, 19 March 2010 The objectives of the workshop is to review the state of the art regarding the fundamental physics of amorphous solids with a stress on their mechanical response to large deformations, including both homogeneous yielding via the elasto-plastic transition and flow localization. These issues are seeing these days interesting scientific progress as advances in both experimental and simulational techniques provide increasingly detailed information about the elementary mechanisms of deformation in diverse systems. They benefit from the many parallels drawn between glasses of dissimilar natures such as metallic glasses, polymeric glasses, pastes, foams, gels,... We will gather leading theoreticians and experimentalists working on metallic, colloidal, and polymeric glasses in order review the state of research in the field. In particular, we will assess what is known vs what is questionable about elementary mechanisms of deformation, we will confront leading theories to experimental and numerical results, and we will question the extent of the similarity (or universality) of behavior between different glasses. We thus hope to spur fruitful exchanges between communities working on different systems, hence having experimental access to broadly different scales and mechanical test conditions. |
