A multi-scale hierarchical constitutive model is developed for establishing the relationship between quantum mechanical, micromechanical, and overall strength/toughness properties in steel design. Focused on the design of ultrahigh strength, high toughness steels, a two-level cell model is used to represent two groups of hard particles (inclusions) in an alloy matrix which is characteristic of such Fe-based alloys. Primary inclusion particles, which are greater than a micron in size, are… CONTINUE READING
