Unsupervised learning for structure detection in plastically deformed crystals
Armand Barbot, Riccardo Gatti
Detecting structures at the particle scale within plastically deformed crystalline materials allows a better understanding of the occurring phenomena. While previous approaches mos…
Coarse-graining amorphous plasticity: impact of rejuvenation and disorder
Botond Tyukodi, Armand Barbot, Reinaldo Garciá-Garciá +3
The coarse-graining of amorphous plasticity from the atomistic to the mesoscopic scale is studied in the framework of a simple scalar elasto-plastic model. Building on recent resul…
Relevance of Shear Transformations in the Relaxation of Supercooled Liquids
Matthias Lerbinger, Armand Barbot, Damien Vandembroucq +1
While deeply supercooled liquids exhibit divergent viscosity and increasingly heterogeneous dynamics as the temperature drops, their structure shows only seemingly marginal changes…
Rejuvenation and Shear-Banding in model amorphous solids
Armand Barbot, Matthias Lerbinger, Anaël Lemaître +2
We measure the local yield stress, at the scale of small atomic regions, in a deeply quenched two-dimensional glass model undergoing shear banding in response to athermal quasistat…
Local yield stress statistics in model amorphous solids
Armand Barbot, Matthias Lerbinger, Anier Hernandez-Garcia +4
We develop and extend a method presented in [S. Patinet, D. Vandembroucq, and M. L. Falk, Phys. Rev. Lett., 117, 045501 (2016)] to compute the local yield stresses at the atomic sc…
