Micromechanical Modeling of Elastic-Viscoplastic Behavior of Armco-Fe at High Strain Rate

引用

Acta Mechanica Solida Sinica 2016年第6期29卷 655-662页

作者： Zhiyong Huang Haomin Wang Qingyuan Wang Muhammad kashif khan School of Aeronautics and Astronautics Sichuan University Faculty of Engineering Environment and Computing Coventry University

Heterogeneous dynamical stress-strain response of Armco-Fe was investigated at high strain rates through the Split Hopkinson Pressure Bar （SHPB） testing. It was found that the viscoplastic deformation in BCC ferrite grains is affected by the strain rate. Thermal softening and variation in crystal orientations under high-strain-rate loading were used in the elastic-viscoplastic modeling. The micromechanical analysis with self-consistent transition and homogenization was used for estimation of the global impact response of the material. The results from modeling were found in good agreement with the experimental data.
