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…

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…

Dynamic fracture of a discrete dissimilar chain: transient, subsonic and supersonic regimes
Nikolai Gorbushin, Gennady Mishuris
This paper deals with the theoretical and numerical analysis of dynamic fracture of dissimilar chain consisting of masses lined by springs. Such a structure exhibits quite differen…
