Digital Material: a flexible atomistic simulation code
Nicholas Bailey, Thierry Cretegny, James P. Sethna +5
The complexities of today's materials simulations demand computer codes which are both powerful and highly flexible. A researcher should be able to readily choose different geometr…
Fracture in Mode I using a Conserved Phase-Field Model
L. O. Eastgate, J. P. Sethna, M. Rauscher +3
We present a continuum phase-field model of crack propagation. It includes a phase-field that is proportional to the mass density and a displacement field that is governed by linea…
Mobility and Reactivity of Discrete Breathers
S. Aubry, T. Cretegny
Breathers may be mobile close to an instability threshold where the frequency of a pinning mode vanishes. The translation mode is a marginal mode that is a solution of the lineariz…
Localization and Equipartition of Energy in the beta-FPU Chain : Chaotic Breathers
Thierry Cretegny, Thierry Dauxois, Stefano Ruffo +1
The evolution towards equipartition in the -FPU chain is studied considering as initial condition the highest frequency mode. Above an analytically derived energy threshold, thi…
