Micromechanical simulation of plastic deformation behavior and failure commencement in high silicon bainitic steel after austempering

The plastic deformation and failure initiation of super bainitic steels containing different amount of bainite were analyzed using a real microstructure-based micromechanical finite element method (FEM). Real micrograph of such phase steels obtained by microscope were utilized as the representative volume elements (RVEs) in the micromechanical approach. Ductile mode of failure throughout selected RVE was simulated in term of strain localization...
