Line-tension model for plasticity as the Gamma-limit of a nonlinear dislocation energy [PDF]
, 2012 In this paper we rigorously derive a line-tension model for plasticity as the Gamma-limit of a nonlinear mesoscopic dislocation energy, without resorting to the introduction of an ad hoc cut-off radius.

Interrelation between Dislocation Loops and an Edge Dislocation
MATERIALS TRANSACTIONS, 2005 Since it has recently become an important subject to study the interrelation between a dislocation loop and a straight edge dislocation because of dynamic behaviors of small dislocation loops under irradiation condition, the simulation studies were made in model Fe lattice.

The study on the effect of the dislocation density on formation of a closed piecewise-continuous dislocation loop in aluminum [PDF]
, 2015 Mathematical model allowing carrying out studies on energy, scale and time characteristics of formation of closed dislocation loop and crystallographic shear zone as a whole, and forming of a dislocation loop for FCC-materials, has been developed.

Microstructural Characterization of Reactor Pressure Vessel Steels
Metals, 2023 Ion irradiation is a promising tool to emulate neutron-irradiation effects on reactor pressure vessel (RPV) steels, especially in the situation of limited availability of suitable neutron-irradiated material.

Annealing of dislocation loops in dislocation dynamics simulations
IOP Conference Series: Materials Science and Engineering, 2009 We report of 3-dimensional discrete dislocation dynamics (DDD) simulations of dislocation loops coarsening by vacancy bulk difiusion. The calculation is based upon a model which couples the difiusion theory of vacancies to the DDD in order to obtain the climb rate of the dislocation segments.

Existence and stability of a screw dislocation under anti-plane deformation [PDF]
, 2014 We formulate a variational model for a geometrically necessary screw dislocation in an anti-plane lattice model at zero temperature. Invariance of the energy functional under lattice symmetries renders the problem non-coercive.

Nano-sized prismatic vacancy dislocation loops and vacancy clusters in tungsten
Nuclear Materials and Energy, 2018 The vacancies produced in high energy collision cascades of irradiated tungsten can form vacancy clusters or prismatic vacancy dislocation loops. Moreover, vacancy loops can easily transform into planar vacancy clusters.

Horizontal instability after acromioclavicular joint reduction using the two-hole technique is preferred over the loop technique: a single-blind randomized clinical trial [PDF]
Clinics in Shoulder and Elbow, 2022 Background Most acromioclavicular joint (ACJ) injuries are caused by direct trauma to the shoulders, and various methods and techniques are used to treat them; however, none of the options can be considered the gold standard.
