Nonsingular stress and strain fields of dislocations and disclinations in first strain gradient elasticity
Markus Lazar, Gerard A. Maugin
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 r…

Peach-Koehler forces within the theory of nonlocal elasticity
Markus Lazar
We consider dislocations in the framework of Eringen's nonlocal elasticity. The fundamental field equations of nonlocal elasticity are presented. Using these equations, the nonloca…

Dislocations in the Field Theory of Elastoplasticity
Markus Lazar
By means of linear theory of elastoplasticity, solutions are given for screw and edge dislocations situated in an isotropic solid. The force stresses, strain fields, displacements,…
