shear bands

On Tuesday 24th October at 3:00 pm (Italian time) Samuel Forest will offer the seminar “Strain gradient plasticity based on saturating internal variables” at the Department of Civil, Environmental, Architectural Engineering and Mathematics of the University of Brescia (Italy). Here attached please find the abstract of the seminar.

Shear banding and stick-slip instabilities have been long observed in sheared granular materials. Yet, their microscopic underpinnings, interdependencies and variability under different loading conditions have not been fully explored. Here, we use a non-equilibrium thermodynamics model, the Shear Transformation Zone theory, to investigate the dynamics of strain localization and its connection to stability of sliding in sheared, dry, granular materials. We consider frictional and frictionless grains as well as presence and absence of acoustic vibrations.
