On the microscopic origin of the plastic spin

Computational issues in large strain elasto‐plasticity: an algorithm for mixed hardening and plastic spin

“…In the case of kinematic hardening without plastic spin (KH) an oscillatory stress prediction is obtained, in contrast with the predictions using the other kinematic hardening models (KH w/PS) and (KH in RS). The presence of oscillatory response in kinematic hardening models is a well known fact also observed experimentally, see for example References [53][54][55][56][57][58] and references therein, and it is not only due to the use of the Jaumann rate as sometimes concluded. The inclusion of a plastic spin in kinematic hardening has been explored in the literature [53][54][55][56][57][58] in order to control the oscillatory response of this type of hardening.…”

The Coupled Theory of Mixtures in Geomechanics with Applications

“…Micro-mechanisms of soils are reported by many researchers (Aifantis 1980(Aifantis , 1984Dafalias 1983Dafalias , 1984Dafalias , 1985Zbib 1993Zbib , 1994Voyiadjis andSong 2005a, 2005b;Song and Voyiadjis 2005a; and many others). Traditional micromechanisms are studied for individual mechanisms.…”

“…His argumentation can also be extended to processes which are partly dissipative or non-dissipative as it has to be assumed in the general case (see [17]). Only the paper by DAFALIAS and AIFANTIS [12] contains some remarks on the possibility of non-symmetric back stresses), however, without discussion of the general thermodynamical background. From the thermodynamical foundations severe restrictions arise with respect to the formulation of evolution laws for internal variables [17 to 191. It may be mentioned that instead of (or additionally to) the rotations itself the gradients of the rotations may enter such a theory.…”
