Non-singular dislocation loops in gradient elasticity

TL;DR

This paper derives non-singular dislocation loop fields in isotropic media using gradient elasticity, providing modified classical formulas for dislocation characterization.

Contribution

It introduces a gradient elasticity framework to obtain non-singular dislocation fields and modifies classical dislocation formulas accordingly.

Findings

Derived non-singular dislocation fields for arbitrary loops

Presented modified Mura, Peach-Koehler, and Burgers formulas

Enhanced understanding of dislocation behavior in gradient elasticity

Abstract

Using gradient elasticity, we give in this Letter the non-singular fields produced by arbitrary dislocation loops in isotropic media. We present the `modified' Mura, Peach-Koehler and Burgers formulae in the framework of gradient elasticity theory.
