Integrability conditions between the first and second Cosserat deformation tensor in geometrically nonlinear micropolar models and existence of minimizers
Johannes Lankeit, Patrizio Neff, Frank Osterbrink
In this note we extend integrability conditions for the symmetric stretch tensor in the polar decomposition of the deformation gradient to the non-symmetric ca…
Existence results in dislocation based rate-independent isotropic gradient plasticity with kinematical hardening and plastic spin: The case with symmetric local backstress
Francois Ebobisse, Patrizio Neff, Daya Reddy
In this paper we use convex analysis and variational inequality methods to establish an existence result for a model of infinitesimal rate-independent gradient plasticity with kine…
A variant of the linear isotropic indeterminate couple stress model with symmetric local force-stress, symmetric nonlocal force-stress, symmetric couple-stresses and complete traction boundary conditions
Ionel-Dumitrel Ghiba, Patrizio Neff, Angela Madeo +1
In this paper we venture a new look at the linear isotropic indeterminate couple stress model in the general framework of second gradient elasticity and we propose a new alternativ…
Correct traction boundary conditions in the indeterminate couple stress model
Patrizio Neff, Ionel-Dumitrel Ghiba, Angela Madeo +1
In this paper we consider the Grioli-Koiter-Mindlin-Toupin indeterminatecouple stress model. The main aim is to show that the traction boundary conditions were not yet completely d…
