An analysis of edge dislocation pileups against a circular inhomogeneity or a bimetallic interface
Equilibrium configurations of edge dislocation pileups against a circular inhomogeneity or a bimetallic interface are determined numerically for a given number N of dislocations, the applied shear stress τ , the size of the inhomogeneity, and the degree of material disparity. The increase of applied stress moves a pileup closer to the inhomogeneity and increases the density of dislocations with...
متن کاملSize-dependent Vibration and Instability of Magneto-electro-elastic Nano-scale Pipes Containing an Internal Flow with Slip Boundary Condition
Size-dependent vibrational and instability behavior of fluid-conveying magneto-electro-elastic (MEE) tubular nano-beam subjected to magneto-electric potential and thermal field has been analyzed in this study. Considering the fluid-conveying nanotube as an Euler-Bernoulli beam, fluid-structure interaction (FSI) equations are derived by using non-classical constitutive relations for MEE material...
متن کاملFinite-size Effects in Fluxon Scattering by an Inhomogeneity
The interaction of a fluxon with a finite-size inhomogeneity in a long Josephson junction is studied within the framework of the perturbation theory for solitons. The threshold values of the bias current density either for capture of the fluxon or for its escape on the inhomogeneity are calculated. Induced by the resonant fluxon emission hystereses on the first zero-field step of the Josephson ...
