Discontinuous yielding of pristine micro-crystals
O. U. Salman, R. Baggio, B. Bacroix +3
We study the mechanical response of a dislocation-free 2D crystal under homogenous shear using a new mesoscopic approach to crystal plasticity, a Landau-type theory, accounting for…

Landau theory of crystal plasticity
R. Baggio, E. Arbib, P. Biscari +4
We show that nonlinear continuum elasticity can be effective in modeling plastic flows in crystals if it is viewed as Landau theory with an infinite number of equivalent energy wel…
