“…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.…”

The present article describes design, architecture, and implementation of the Aachen ("Aix") Virtual Platform for Materials Processing-AixViPMaP ®. This simulation platform focuses on enabling automatic simulation workflows in the area of microstructure evolution and microstructure property relationships by continuum models. Following a description of a variety AixViPMaP® functionalities like user management, the currently implemented software tools, simulation workflows, data storage, grid infrastructure, and many more, some example workflows which have been run on AixViPMaP® are presented in detail. These workflow examples-although each being specific-can readily be transferred to other materials or to similar processes as the major simulation tools used in these workflows are all generic and thus applicable to a wide range of metals and technical alloys. The article concludes with a discussion on the performance and benefits of the platform, an outlook on its future development and on its open, future availability for both academic and commercial use.

“…The determined effective thermo‐elastic properties are necessary input for structural and/or process simulation tools at the macro‐scale. This way, coupled micro‐macro analyses of the material behaviour along a whole manufacturing process chain becomes possible on a virtual process simulation platform 15.…”

A multi-scale approach based on the asymptotic homogenization method of periodic material structures is applied here to determine the effective thermo-elastic properties of 3D steel microstructures, which have been calculated by phase-field simulations. A multiphase-field model, coupled to thermodynamic databases, is used to evaluate the microstructure evolution during the austenite to ferrite phase transformation of low carbon Fe-C-Mn steel. In order to derive effective mechanical properties, geometrical information about the grains, their phase properties and crystallographic orientations are transferred to the homogenization tool. Effective cubic Young and shear modules and Poisson coefficients are predicted for different ferrite volume fractions. Moreover, the volume change is derived as function of the phase fractions, leading to a calculated dilatometer curve. The effects of the thermal shrinkage and the volume expansion caused by the phase transformation are taken into account.
