Fluctuations in crystalline plasticity
Jérôme Weiss, Peng Zhang, Oguz Umut Salman +2
Recently acoustic signature of dislocation avalanches in HCP materials was found to be long tailed in size and energy, suggesting critical dynamics. Even more recently, the intermi…
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…
Frictionless motion of lattice defects
N. Gorbushin, G. Mishuris, L. Truskinovsky
Energy dissipation by fast crystalline defects takes place mainly through the resonant interaction of their cores with periodic lattice. We show that the resultant effective fricti…
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…
Rigidity-Controlled Crossover: From Spinodal to Critical Failure
Hudson Borja da Rocha, Lev Truskinovsky
Failure in disordered solids is accompanied by intermittent fluctuations extending over a broad range of scales. The implied scaling has been previously associated with either spin…
