Interaction energy of interface dislocation loops in piezoelectric bi-crystals
Theoretical and Applied Mechanics Letters, 2017 Interface dislocations may dramatically change the electric properties, such as polarization, of the piezoelectric crystals. In this paper, we study the linear interactions of two interface dislocation loops with arbitrary shape in generally anisotropic ...

Optimisation of the parameters of an extended defect model applied to non-amorphizing implants [PDF]
, 2005 In this paper, we present the optimisation of the parameters of a physical model of the kinetics of extended defects and applied the model with the optimised parameters to non-amorphizing implants.

Strain Localisation and Fracture of Nuclear Reactor Core Materials
Journal of Nuclear Engineering, 2023 The production of prismatic dislocation loops in nuclear reactor core materials results in hardening because the loops impede dislocation motion. Yielding often occurs by a localised clearing of the loops through interactions with gliding dislocations ...

Large scale ab-initio simulations of dislocations [PDF]
, 2019 We present a novel methodology to compute relaxed dislocations core configurations, and their energies in crystalline metallic materials using large-scale ab-intio simulations. The approach is based on MacroDFT, a coarse-grained density functional theory

Movement of Dislocation Loops in Lithium Fluoride
Journal of Applied Physics, 1958 Very refined experiments on the movement of single dislocation loops in lithium fiuoride crystals, as revealed by etch pits, have been reported. In this note a somewhat more detailed interpretation is given for one particularly signiflcant experiment. (W.D.M.)

Unraveling deformation mechanisms around FCC and BCC nanocontacts through slip trace and pileup topography analyses [PDF]
, 2017 Nanocontact loadings offer the potential to investigate crystal plasticity from surface slip trace emissions and distinct pileup patterns where individual atomic terraces arrange into hillocks and symmetric rosettes.
