Mesoscale plastic strain localization in a titanium alloy with a modified surface layer

Abstract

An experimentally supported numerical simulation is performed to investigate the mesoscale stress-strain localization in a surface-modified commercial titanium alloy (VT1-0 according to Russian classification). The calculated crystalline microstructure corresponds to that observed in experiments and is accounted for in an explicit way as initial conditions of a dynamic boundary-value problem. The latter is stated in terms of plane strain developing in microstructure subjected to tension and is solved numerically by the finite-difference method. Elastic-plastic constitutive models were built to describe the experimental mechanical response both of the substrate and of the modified layer. Plastic strain localization is found to depend on the grain yield strength.
