The observation reveals that the planar and wrinkled GNPs in the composite act as the effective trigger of dislocations and collector of solute atoms to accelerate the precipitation.
The generation of a twin can be triggered by dislocations at grain boundaries.
We found that interfacial crack nucleation is triggered by heterogeneous dislocation nucleation.
In this work, we demonstrate by experiments and molecular dynamic simulations that the novel intersectant coherent twin boundaries (i-CTBs) involving Lomer-Cottrell (L-C) dislocation locks trigger off a strong strain hardening on nanostructured metal, which exceeds the strength induced by p-CTBs strengthening.
This difference of strain energy can be attributed to the entirely different dislocation activities triggered by nanoindentation on three different surfaces.
Symmetrical trapezoidal prismatic blocks, with the major and the minor sides being equal to 4 and 2 base heights, respectively, are attached to the base at regular intervals along the span which could be varied in order to render multiple wavelengths of spanwise discontinuity to ensure that at least one of the modes of dislocation is triggered independent of the Reynolds number.
During loading, prominent multiple pop-ins, or sudden displacement excursions are triggered by discontinuous yielding from dislocation nucleation and motion.
As addressed in heteroepitaxial layers, specific analogous characterization exists either in dislocation activities or by triggering crack formation.
Previous shoulder surgery, pathology in the opposite shoulder, history of injury, direction and degree of instability, duration of symptoms, minimum activity level to trigger instability symptoms, and number of dislocations were recorded.
His work -- like Kate Yourke's "Hypnagogic Nostalgia: Home Is Where the Hearth Is," which also uses video to inject narrative -- plays with the dichotomy between domestication and dislocation, using familiar landmarks to trigger private emotional responses.
