Material modelling as a tool for the quality assurance and product development of heavy plate steels for steel construction

Shorter product development cycles and compliance with exact process parameters during the production of high-strength heavy plate for heavy machine construction requires fast modelling of mechanical and technological material properties during the actual production process. To this end, the Heavy Plate Unit at ThyssenKrupp Steel Europe AG has used state-of-the-art calculation tools from collections of process data and test value databases. This report describes the step-by-step development of the underlying material models, their implementation in practical computer software and their practical application illustrated by some selected examples.
