this paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. a laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...

In phase-field models the damage evolution problem is considered as a minimisation of Griffith-like energy functional, governed by principles irreversibility, stability and balance. Herein, we consider characterised different degradation dissipation functions. With proper choice for characteristic functions in models, it possible to reproduce cohesive fracture one-dimensional setting. We bar wi...
