Towards integrative computational materials engineering of steel components

Abstract

This article outlines on-going activities at the RWTH Aachen University aiming at a standardized, modular, extendable and open simulation platform for materials processing. This platform on the one hand facilitates the information exchange between different simulation tools and thus strongly reduces the effort to design/re-design production processes. On the other hand, tracking of simulation results along the entire production chain provides new insights into mechanisms, which cannot be explained on the basis of individual simulations. Respective simulation chains provide e.g. the basis for the determination of materials and component properties, like e.g. distortions, for an improved product quality, for more efficient and more reliable production processes and many further aspects. After a short introduction to the platform concept, actual examples for different test case scenarios will be presented and discussed

AixViPMaP®—an Operational Platform for Microstructure Modeling Workflows

“…An early feasibility study for the AixViPMaP® platform [3,4] essentially allowed for the configuration of some dedicated simulation chains for steels [5][6][7], but also for polymers and composites [4]. Major limitations of this first approach were essentially due to the use of VTK [8] as communication standard, which focused on the description of 3D fields representing microstructures but did not allow to coherently include other data like statistics or metadata.…”

Modeling steel rolling processes by fluid-like differential equations

“…Due to the required high spatial resolution, these models are usually coupled with process models that calculate the complete thermo-mechanical problem posed by rolling process by FEM [2]. Through-process models are an important part of the emerging field of Integrated Computational Materials Engineering (ICME), which has recently been put forward as a methodology to support efficient and cost-effective materials and process design [27].…”
