Transition fronts and their universality classes
N. Gorbushin, A. Vainchtein, L. Truskinovsky
Steadily moving transition (switching) fronts, bringing local transformation, symmetry breaking or collapse, are among the most important dynamic coherent structures. The nonlinear…
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…
Influence of fracture criteria on dynamic fracture propagation in a discrete chain
Nikolai Gorbushin, Gennaro Vitucci, Grigory Volkov +1
The extent to which time-dependent fracture criteria affect the dynamic behavior of fracture in a discrete structure is discussed in this work. The simplest case of a semi-infinite…
On admissible steady-state regimes of crack propagation in a square-cell lattice
Nikolai Gorbushin, Gennady Mishuris
In the present work the authors revisit a classical problem of crack propagation in a lattice. Authors investigate the questions concerning possible admissible steady-state crack p…
Dynamic fracture of a discrete media under moving load
Nikolai Gorbushin, Gennady Mishuris
Most of the research concerting crack propagation in discrete media is concerned with specific types of external loading: displacements on the boundaries, or constant energy fluxes…
Analysis of dynamic failure of the discrete chain structure with non-local interactions
Nikolai Gorbushin, Gennady Mishuris
In the present work the steady-state crack propagation in a chain of oscillators with non-local interactions is considered. The interactions are modeled as linear springs while the…
