Abstract
Yield-point phenomena in Ferrite–Pearlite duplex steels were investigated using multi-scale computational simulations. In this multi-scale simulations, stress–strain relationship of Ferrite phase was characterized by an elastoplastic constitutive model considering yield-drop behavior and its material constants were determined by minimizing residual error between a computational simulation and experiment of tensile test, where yield-point phenomenon in a tensile test of Ferrite steel was reproduced.
期刊介绍：
The journal ISIJ International first appeared in 1961 under the title Tetsu-to-Hagané Overseas. The title was changed in 1966 to Transactions of The Iron and Steel Institute of Japan and again in 1989 to the current ISIJ International.
The journal provides an international medium for the publication of fundamental and technological aspects of the properties, structure, characterization and modeling, processing, fabrication, and environmental issues of iron and steel, along with related engineering materials.
