Ferrous Material Models in Computational Engineering

A perceptive review of progress observed in development of ferrous materials models for computational engineering applications is presented.

In this recently published article in steel research international, Lukasz Madej and Maciej Pietrzyk from AGH University of Science and Technology provide a perceptive review of progress observed in development of ferrous materials models for computational engineering applications. Development of material models with different levels of complexities during last forty years of research is generally presented. Particular attention is put on distinguishing the two major approaches called mean field and full field models. Selected micro and macro scale models are presented and discussed within the paper. Evolution of conventional mean field models based on closed form or differential equations is described first to demonstrate the progression in thinking of new engineering materials. This part of the work clearly presents how increasing knowledge on materials behaviour under thermo – mechanical treatment conditions, coming from extensive, sophisticated experimental research, influences progress in development of more complex numerical models.

Eventually, this progress led to the concepts of the multi scale modelling or even further to the integrated computational material engineering. Thus, the second part of the paper is devoted to a short description of recent progress and selected advancements in development of full field and multi scale modelling solutions. This part highlights the enormous amount of research that is presently carried out in the area of computational materials science. Finally, capabilities, as well as, limitations and drawbacks of both groups of models are discussed on the basis of selected case studies. The future problems that have to be taken into account during development of new generation of material models are also pointed out.
