Sentence examples for mobile dislocation density from inspiring English sources

The chapter discusses the investigations on the dislocation mobility and mobile dislocation density (that is, in a manner correlated to dislocation exhaustion) in the intermetallics Ni3Al and γ-TiAl.

An estimate of the related heterogeneous evolution of the mobile dislocation density was also obtained.

The relationship between mobile dislocation density and strain hardening exponent was discussed based on the dislocation-stress relation.

The results indicate that a change in the mobile dislocation density, together with thermal softening, has substantial effects on apparent work hardening behavior at high strain rates, although the change in the mobile dislocation density is transcribed at macroscopic scale in the model.

Stress-relaxation experiments were performed on nanotwinned Cu to characterize the twin size-dependence of the activation volume and mobile dislocation density.

The inelastic deformation is predicted based on the mobile dislocation density, and the immobile dislocation density is adopted to predict the evolution of yield surface.

The GB scheme is based on slip-system compatibility, local resolved shear stresses, and immobile and mobile dislocation-density accumulation at critical GB locations.

The balance between the generation and annihilation of dislocations, through glissile and forest interactions at the slip system level, is taken as the basis for the evolution of mobile and immobile dislocation densities.

At the second scale, a novel meso-scale simulation (MSS) redistributes the mobile part of the dislocation density within grains consistent with the plastic strain, computes the associated inter-dislocation back stress, and enforces local slip transmission criteria at grain boundaries.

Based on these observations, equations for the evolution of mobile and forest dislocation densities are posed, depicting boundary sources and dislocation dislocation interactions, respectively.

The dislocation density is divided into mobile and immobile parts.
