Self-Organization of Adiabatic Shear Bands in Copper and Steel

In this work we consider the self-organization process of adiabatic shear bands (ASB) formation in OFHC copper and HY-100 steel taking into account the strain hardening factor. We proposed the numerical approach which is based on the Courant-Isaacson-Rees scheme. Using this method we made a numerical investigation, in which it was shown that the strain hardening process leads to the increase in the localization time and to a decrease the number of ASB formed. Using the fact, that the processes of ASB formation are quasi-periodic, we obtained a numerical estimate of the distance between ASB and compared our numerical results with theoretical estimates by others.
