Dynamic stress response kernels for dislocations and cracks: unified anisotropic Lagrangian formulation
Yves-Patrick Pellegrini, Marc Josien, Martin Chassard
Elastodynamic cohesive-zone models for defects such as cracks or dislocations (such as the Geubelle-Rice model for cracks, or the Dynamic Peierls Equation for flat-core dislocation…
Shock-driven nucleation and self-organization of dislocations in the dynamical Peierls model
Yves-Patrick Pellegrini, Marc Josien
Dynamic nucleation of dislocations caused by a stress front ('shock') of amplitude moving with speed is investigated by solving numerically the Dynamic Peierls Equa…
Dynamic Peach-Koehler self-force, inertia, and radiation damping of a regularized dislocation
Yves-Patrick Pellegrini
The elastodynamic Peach-Koehler force is computed for a fully-regularized straight dislocation with isotropic core in continuum isotropic elastic elasticity, in compact forms invol…
Uniformly-moving non-singular dislocations with elliptical core shape in anisotropic media
Yves-Patrick Pellegrini
To allow for `relativistic'-like core contraction effects, an anisotropic regularization of steadily-moving straight dislocations of arbitrary orientation is introduced, with two s…
Fourier-based numerical approximation of the Weertman equation for moving dislocations
Marc Josien, Yves-Patrick Pellegrini, Frédéric Legoll +1
This work discusses the numerical approximation of a nonlinear reaction-advection-diffusion equation, which is a dimensionless form of the Weertman equation. This equation models s…
Causal Stroh formalism for uniformly-moving dislocations in anisotropic media: Somigliana dislocations and Mach cones
Yves-Patrick Pellegrini
In this work, Stroh's formalism is endowed with causal properties on the basis of an analysis of the radiation condition in the Green tensor of the elastodynamic wave equation. The…
