In the theory of dislocations, the Burgers vector is usually defined by referring to a crystal structure. Using the notion of affine development of curves on a differential manifold with a connection, we give a differential geometric definition of the Burgers vector directly in the continuum setting, without making use of an underlying crystal structure.
The Research Center for Mechanics of Solids, Structures and Materials at the University of Texas at Austin invites applications for an open position as Post-doctoral Fellow. The specific project involves the characterization of the constitutive and failure behavior of structural materials (aluminum alloys, steels, titanium alloys, metal-matrix composites, polymers and other selected materials) under quasi-static and dynamic conditions.

After many publications and lecture notes, Prof. Ian Murdoch has finally organized much of that material in the form of a book.
I am very hopeful that like Prof. Murdoch's lectures, this monograph will also help the readers to develop a better understanding of the physical aspects of mechanics. It will be a valuable addition to the researchers' personal collection.

The long range elastic interaction between dislocations is naturally accounted in
discrete dislocation plasticity through stress field of individual dislocation.
In addition, the dislocation boundaries elastic interaction is considered via
image stress superposition approach in the finite element framework. In current
study these interaction terms are considered in crystal plasticity framework
through length scale dependent internal residual stresses which are arise from
