3-D discrete dislocation dynamics simulations were used to investigate the size-dependent
plasticity in polycrystalline, free-standing, thin films. A simple line-tension model was used to …

Discrete dislocation dynamics simulations are carried out to systematically investigate the
microstructural and geometrical size dependence of films under tension that have a varying …

The plastic deformation of polycrystalline fcc metal thin films with thicknesses of 1 μm and
less is investigated by simulating the dynamics of discrete dislocations in a representative …

A method is proposed to estimate the size-dependent yield strength of columnar-grained
freestanding thin films. The estimate relies on assuming a distribution of the size of Frank …

Two-dimensional discrete dislocation plasticity simulations of the evolution of thermal stress
in single crystal thin films on a rigid substrate are used to study size effects. The relation …

Equations for dislocation evolution bridge the gap between dislocation properties and
continuum descriptions of plastic behavior of crystalline materials. Computer simulations can …

Strong size effects have been experimentally observed when microstructural features
approach the geometric dimensions of the sample. In this work experimental investigations …

Stress development and relaxation in polycrystalline thin films perfectly bonded to a stiff
substrate is analyzed numerically. The calculations are carried out within a two-dimensional …

Three-dimensional dislocation dynamics simulations were used to examine the role of
surface passivation on the plasticity of thin films. A simple line-tension model was used to …

Plastic deformation of thin metal films has been investigated with the help of a discrete
dislocation dynamics simulation. In particular, the operation of a Frank-Read source was …
