Effects of relaxation and pre-history in the course of plastic twisting

The effect of temporal delay and relaxation on the structural order parameter (OP) in the course of plastic deformation by twisting is theoretically analyzed. It is shown that an anomalous behavior of the OP modulus takes place. The analysis is based on the Landau-Khalatnikov equation. •The effect o...

Description
Summary:The effect of temporal delay and relaxation on the structural order parameter (OP) in the course of plastic deformation by twisting is theoretically analyzed. It is shown that an anomalous behavior of the OP modulus takes place. The analysis is based on the Landau-Khalatnikov equation. •The effect of plastic deformation by twisting on crystals is studied.•The delay (prehistory) and relaxation processes are taken into account.•These factors explain the observed behavior of the structural order parameter.
