Webb14 apr. 2024 · Charge and spin density waves are typical symmetry broken states of quasi one-dimensional electronic systems. They demonstrate such common features of all incommensurate electronic crystals as a spectacular non-linear conduction by means of the collective sliding and susceptibility to the electric field. These phenomena ultimately … Webb12 feb. 1998 · A quantitative description of plastic deformation in crystalline solids requires a knowledge of how an assembly of dislocations — the defects responsible for crystal plasticity — evolves under ...

To observe plasticity of grain boundaries independently of the bulk plasticity, we simulate nanoindentation of bicrystals. On the low angle twist boundaries, the intrinsic grain boundary (GB) dislocation network deforms …

Download it once and read it on your Kindle device, PC, phones or tablets. … WebbThe non-linear continuum theory of dislocations has been used to solve a number of problems for isotropic materials, including the determination of stresses produced by dislocations, the scattering of elastic waves by straight dislocations and kinks, and the small-angle scattering of X-rays by dislocation lines and rings.
Webb13 juni 2001 · 1.. IntroductionThe dislocation theory has been developed during decades of intensive research. The excellent reviews of this research can be, for example, found in [1], [2].The main difficulty in application of the theory to real materials is a necessity to take into consideration the interactions among multiple dislocations with different … WebbChapter 2 details the models of dislocation self interaction for curved dislocations including the line tension model and linear elastic self interaction. The former is …

This theory is a kind of axiomatic field theory of dislocations. The nature of such a general dislocation theory is geometrically nonlinear. flouting pronunciationWebbrange interactions between dislocations are calculated through theory of elasticity; short range interactions are determined based on local rules. DDD is implemented either in two- or three-dimensional frameworks. Three-dimensional DDD (3d DDD) includes dislocations in realistic geometries and many dislocation phenomena such as greek battleship lemnos
