Derivation of a line-tension model for dislocations from a nonlinear three-dimensional energy: The case of quadratic growth

A Garroni, R Marziani, R Scala - SIAM Journal on Mathematical Analysis, 2021 - SIAM
In this paper we derive a line tension model for dislocations in 3D starting from a
geometrically nonlinear elastic energy with quadratic growth. In the asymptotic analysis, as …

Characterization of Generalized Young Measures Generated by -free Measures

A Arroyo-Rabasa - Archive for rational mechanics and analysis, 2021 - Springer
We give two characterizations, one for the class of generalized Young measures generated
by\, A\, A-free measures and one for the class generated by B B-gradient measures B u B u …

Long range order in atomistic models for solids

A Giuliani, F Theil - Journal of the European Mathematical Society, 2021 - ems.press
The emergence of long range order at low temperatures in atomistic systems with
continuous symmetry is a fundamental, yet poorly understood phenomenon in physics. To …

Atomistic origins of continuum dislocation dynamics

T Hudson, P van Meurs, M Peletier - Mathematical Models and …, 2020 - World Scientific
This paper focuses on the connections between four stochastic and deterministic models for
the motion of straight screw dislocations. Starting from a description of screw dislocation …

On the motion of curved dislocations in three dimensions: simplified linearized elasticity

I Fonseca, J Ginster, S Wojtowytsch - SIAM Journal on Mathematical Analysis, 2021 - SIAM
It is shown that in core-radius cutoff regularized simplified elasticity (where the elastic energy
depends quadratically on the full displacement gradient rather than its symmetrized version) …

[PDF][PDF] Defining creation in 1D dislocation dynamics

J Moraal - pure.tue.nl
We consider an interacting particle system with singular interaction, describing the dynamics
of finite numbers of (charged) dislocations in one-dimensional space, including annihilation …
