Molecular Simulations of Shock to Detonation Transition in Nitromethane
J. -B. Maillet, G. Vallverdu, N. Desbiens +1
An extension of the model described in a previous work of Maillet, Soulard and Stoltz based on a Dissipative Particule Dynamics is presented and applied to liquid nitromethane. Lar…
Reply to "Comment on 'Dynamic Peierls-Nabarro equations for elastically isotropic crystals' "
Yves-Patrick Pellegrini
The Comment by Markenscoff that criticizes a recent dynamic extension of the Peierls-Nabarro equation [Y.-P. Pellegrini, Phys. Rev. B 81, 024101 (2010)] is refuted by means of simp…
The melting curve of iron at extreme pressures: implications for planetary cores
G. Morard, J. Bouchet, D. Valencia +2
Exoplanets with masses similar to that of Earth have recently been discovered in extrasolar systems. A first order question for understanding their dynamics is to know whether they…
Inertial and retardation effects for dislocation interactions
L. Pillon, C. Denoual
A new formulation for the equation of motion of interacting dislocations is derived. From this solution it is shown that additional coupling forces, of kinetic and inertial origin,…
Phase-Field Reaction-Pathway Kinetics of Martensitic Transformations in a Model Fe3Ni Alloy
Christophe Denoual, Anna Maria Caucci, Laurent Soulard +1
A three-dimensional phase-field approach to martensitic transformations that uses reaction pathways in place of a Landau potential is introduced and applied to a model of Fe3Ni. Pa…
On probabilistic aspects in the dynamic degradation of ductile materials
Herve Trumel, Francois Hild, Gilles Roy +2
Dynamic loadings produce high stress waves leading to the spallation of ductile materials such as aluminum, copper, magnesium or tantalum. The main mechanism used herein to explain…
