Sentence examples for dislocation systems from inspiring English sources

The transition from stochastic to deterministic, bulk-like behavior in sub-micron Mo-alloy pillars may therefore be related to an increasing number of multiple a〈1 1 1〉 dislocation systems within the Mo fibers with increasing pre-strain, considering that the bulk-like behavior is governed by the forest hardening of these junctions.

Problems of nucleation and evolution of multiple dislocations along the single and multiple slip systems near martensitic lath, and along the sharp austenite –martensite interface, the activity of dislocations with two different orientations in a nanograined material under shear and pressure, and the interaction between two intersecting dislocation systems are studied.

This fundamental setting provided by the classical continuum theory of dislocation systems has, over the past two decades, inspired many models (e.g. (Sedláček et al. 2003; Xiang 2009; Zhu and Xiang 2015)).

The method is applied to an Ir weld sample to illustrate how microdiffraction can be used to determine the locally active dislocation system.

We therefore use a description of the dislocation system by slip system specific dislocation density vectors as the starting point of our subsequent discussion.

This theory describes the dislocation system in terms of a rank-2 tensor field α defined as the curl of the plastic distortion, α=∇×β p l.

Although in DDD simulations, artificial Frank-Read sources are often used to populate a dislocation system in early stages, we consider samples with sufficient initial dislocation density where network sources (glissile junctions) are expected to dominate dislocation multiplication.

The formulation in terms of alignment tensors has proven particularly versatile since one can formulate the elastic energy functional of the dislocation system in terms of dislocation density alignment tensors (Zaiser 2015) and then use this functional to derive the dislocation velocity in a thermodynamically consistent manner (Hochrainer 2016).

The first Phase Field model of evolution of a multi-dislocation system in elastically anisotropic crystal under applied stress is formulated.

With increasing strain, double twins and stacking faults form and a number of dislocation slip systems are activated, including basal plane systems, prismatic plane systems and pyramidal plane systems.

The dislocation slip systems emitted and transmitted across the interfaces are strongly linked to the interface structure and crystallography.
