Sentence examples for mobility of screw from inspiring English sources
The mobility of screw and non-screw segments are defined in a phenomenological manner.
Therefore, the accurate prediction of kink nucleation energies is required to fully describe mobility of screw dislocations in these materials.
The necessity of applying high stress in sub-micron crystals is demonstrated to greatly enhance the mobility of screw dislocations, rendering it close to that of edge dislocations.
Thus, the flow stress gradually becomes not governed by the mobility of screw dislocations (as determined by the critical resolved shear stress), giving rise to the weak temperature sensitivity of the flow stress.
Thermal activation apparently increases the mobility of screw segments, and results in dislocation structures containing mixed dislocations with no preferred orientation; this signals the onset of the brittle-ductile transition between 700 and 900°C.
Assuming the flow stress to be controlled at low temperatures by the mobility of screw dislocations and by forest interactions at high temperatures, this model allows for the prediction of the mechanical behavior in monotonic loading over a large range of temperatures and strain rates.
Large-scale first-principles calculations were performed to determine the stability and mobility properties of screw dislocations in common silicon carbide polytypes (4H, 2H and 3C).
In this paper, a half-space Peierls Nabarro (HSPN) model is proposed to re-examine the mobility of a screw dislocation along a thin film/substrate (half-space) interface.
A better grip reduces the mobility of the screws, and this reduces the loosening, the inflammation and the possibilities of infection.
Studies of dislocations under applied load reveal marked difference in mobilities of the screw and edge dislocations that are consistent with experimental observations.
Developed in this note is a theoretical model describing the mobility of a misfit screw dislocation dipole in a wire composite consisting of a stiff cylindrical substrate covered by a soft co-axial cylindrical film.
