Influence of multiscale localized plastic flow on stress-strain patterns
Source abstract
Abstract
The paper considers the influence of multiscale plastic flow localization on rotational deformation modes and σ-ɛ curves by analyzing the entropy production and equation of state of a deformed solid. It is shown that if the rotational deformation modes are fully self-consistent, the σ-ɛ curve changes monotonically. If not, the curve reveals jerks or serrations due to nonlinear wave relaxation of stresses associated with macroscale non-compensated material rotations. At high loading rates, the rotational deformation modes attain self-consistency by the mechanism of dynamic rotations.
