Local Strain Measurements at Dislocations, Disclinations and Domain Boundaries
High-resolution images can be analysed by geometric phase analysis (GPA) [3] or applying peak-finding routines to determine the positions of individual atomic columns. GPA is best adapted to measuring the deformation of the crystalline lattice, as the example concerning a five-fold twinned Pt nanoparticle will show (Figure 1). These star-shaped particles [4] have a disclination-like strain fiel...
متن کاملPlane Strain Dislocations in Linear Elastic Diffusive Solids
Solutions are obtained for the stress and pore pressure due to sudden introduction of plane strain dislocations in a linear elastic, fluid-infiltrated, Biot, solid. Previous solutions have required that the pore fluid pressure and its gradient be continuous. Consequently, the antisymmetry (symmetry) ofthe pore pressure p about y = Orequires that this plane be permeable (p = 0) for a shear dislo...
متن کاملNonsingular stress and strain fields of dislocations and disclinations in first strain gradient elasticity
The aim of this paper is to study the elastic stress and strain fields of dislocations and disclinations in the framework of Mindlin’s gradient elasticity. We consider simple but rigorous versions of Mindlin’s first gradient elasticity with one material length (gradient coefficient). Using the stress function method, we find modified stress functions for all six types of Volterra defects (dislo...
متن کاملInterface Effects on Screw Dislocations in Heterostructures
The governing equation of screw dislocations in heterostructures is constructed using image method. The interface type (−1 ≤ γ ≤ 1) and distance between dislocation and interface h are considered in the new equation. The Peierls–Nabarro equations for screw dislocations in bulk and semi-infinite materials can be recovered when γ = 0 and γ = −1. The soft (γ < 0) and hard (γ > 0) interfaces can en...
متن کاملDislocations & Fractures
tit r* -By F. J. Cotton. vv. a. Saunders & Co. Under this title Dr. Frederick Cotton has compiled a text-book on the subject of injuries to bones and joints which should certainly take its place as a standard work. The author has amply illustrated his subject, and in fact relies on illustration almost as much as letter press to make his subject clear, for in GOO odd pages there are 1,200 or mor...
