INTEGRATED EXPERIMENTAL AND SIMULATION ANALYSIS OF STRESS AND STRAIN PARTITIONING IN DUAL PHASE STEEL

摘要

The mechanical behavior of multiphase steels is governed by the microscopic strain and stress partitioning behavior among microstructural constituents [1-3]. However, due to limitations in the characterization of the partitioning that takes place at the submicron scale, microstructure optimization of such alloys is typically based on evaluating the averaged response, referring to, for example, macroscopic stress-strain curves.
