In situ X-ray diffraction peak profile analysis during plastic deformation in [001] oriented
copper single crystals was carried out using synchrotron radiation. Characteristic changes of …

The background intensity of X-ray diffraction patterns is analysed in terms of point defects,
especially vacancies, in poly-and single-crystalline copper specimens. The samples have …

A new dislocation-based model for low cycle fatigue in fcc metals at a length scale smaller
than the feature size of the dislocation structures is presented. It uses the crystal plasticity …

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

The major cause of anisotropic plastic response in polycrystalline metals is crystallographic
texturing resulting from the reorientation of the crystal lattices of grains during deformation …

Three known dislocation density based models are compared to each other, and to
available experimental results. All three models were embedded into ANSYS finite element …

According to materials scientist and philosopher Cyril Stanley Smith, the structure of
materials is best described as a multilevel architecture, with “interplay of perfection and …

Substructure evolution has been studied by transmission electron microscopy in cyclically
deformed copper polycrystals during conventional strain control testing and ramp loading. In …

A copper sample made of a single layer of grains is plastically deformed by uniaxial tension
at room temperature and low strain rate. The deformation field is measured by means of …

Most engineering materials possess a polycrystalline structure. Under load the anisotropy of
the constituent grains leads to strong inhomogeneities of stresses and strains on the grain …
