Title: Numerical modeling of the thermomechanical behavior of steels with allowance for the propagation of Luders bands.
Authors: Balokhonov, R. R.; Romanova, V. A.
Abstract: A thermomechanical model based on physical representations of the motion of dislocation continuum and a model for the initiation and propagation of plastic shear are proposed to describe slow flows of the type of Luders bands. Two-dimensional calculations of Luders band propagation are performed for HSLA-65 steel samples under compression at various strain rates and temperatures. The calculation results are in good agreement with experimental data.
