Micro-and nanomechanical testing has seen a rapid development over the last decade with
miniaturized test rigs and MEMS-based devices providing access to the mechanical …

It has been widely recognized that the fatigue performance of metallic materials is
significantly affected by both geometrical and microstructural sizes. Based on a literature …

Both torsion and tensile tests are performed on polycrystalline copper wires with diameters
in the range 20–50μm. A significant size effect in both the initial yielding and the plastic flow …

The review is dedicated to characteristics of the mechanical behavior of various materials at
submicro-and nanoscale levels. To a large extent, progress in this area is determined by the …

Under small strains and rotations, we apply a phenomenological higher-order theory of
distortion gradient plasticity to the torsion problem, here assumed as a paradigmatic …

The plasticity of micron scale Cu and Au wires under cyclic torsion is investigated for the first
time<? format?> by using a torsion balance technique. In addition to a size effect, a distinct …

Although presenting attractive features in dealing with small-scale size effects, strain
gradient plasticity (SGP) theories can lead to uncommon phenomena for some boundary …

A numerical implementation of a non-local polycrystal plasticity theory based on a
mesoscale version of the field dislocation mechanics theory (MFDM) of Acharya and Roy …

Fatigue failure through sustained loading of ductile materials manifests in irreversible motion
of dislocations, followed by crack initiation and growth. This contrasts with the mechanisms …

We study the Bauschinger effect on a bent and straightened micro-sized single-crystal
copper beam (width: 8.64 μm; thickness: 7.05 μm) over three consecutive cycles. The …
