Self-induced marginality in plastically deformed crystals
Oguz Umut Salman, Aylin Ahadi, Lev Truskinovsky
Quasi-brittle plastic yielding is a salient feature of well-annealed glassy materials. Here we show that the same behavior is characteristic of perfect crystals after they experien…
Homogeneous nucleation of dislocations as a pattern formation phenomenon
R. Baggio, O. U. Salman, L. Truskinovsky
Dislocation nucleation in homogeneous crystals initially unfolds as a linear symmetry-breaking elastic instability. In the absence of explicit nucleation centers, such instability…
Inelastic rotations and pseudo-turbulent plastic avalanches in crystals
R. Baggio, O. U. Salman, L. Truskinovsky
Plastic deformations in crystals often produce textures in the form of randomly oriented patches of the unstressed lattice. We use a novel mesoscopic Landau-type model of crystal p…
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…
De-localizing brittle fracture
O. U. Salman, L. Truskinovsky
Extreme localization of damage in conventional brittle materials is the source of a host of undesirable effects. We show how artificially engineered metamaterials with all brittle…
Variety of scaling behaviors in nanocrystalline plasticity
P. Zhang, O. U. Salman, J. Weiss +1
We address the question of why larger, high symmetry crystals are mostly weak, ductile and statistically sub-critical, while smaller crystals with the same symmetry are strong, bri…
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…
