摘要

采用多尺度计算模拟方法研究了铁素体-珠光体双相钢的屈服点现象。在多尺度模拟中，采用考虑屈服下降行为的弹塑性本构模型表征铁素体相的应力-应变关系，并通过最小化拉伸试验计算模拟与实验之间的残余误差确定其材料常数，再现了铁素体钢拉伸试验中的屈服点现象。

Multiscale Finite Element Analysis of Yield-point Phenomenon in Ferrite–Pearlite Duplex Steels

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.
