Virtual Joining Factory – Integration of microstructure evolution in the manufacturing process chain simulation Ulrike Beyer1, a *, Ingo Neubauer1, b, Johannes Kreyca2, c, Ernst Kozeschnik2, d 1Simufact Engineering GmbH, Germany 2Institute of Materials Science and Technology, Vienna University of Technology, Austria aulrike.beyer@simufact.de, bingo.neubauer@simufact.de, cjohannes.kreyca@tuwien.ac.at, dernst.kozeschnik@tuwien.ac.at Keywords: FEM, Simulation, Material Calculation, Joining, Self-Piercing Riveting, Virtual Factory Introduction Over the past years engineering has established itself in many areas of production technology on the basis of simulation methods.
MatCalc. stands for „Material Calculator“ and describes the original vision of being able to universally describe and predict the development of the microstructure of metallic materials in the course of its manufacturing and application with the help of theoretical models.
Furthermore, information on the mechanical-thermal characteristics of the used materials is needed, which are often gained by practical trials.
Furthermore, the materials which shall be joined with the self-piercing rivet have to be defined at first for the forming and cutting process.

Generally welding-related data is applied to almost all metallic materials as well as many types of welding methods are being developed.
Also, the developed system, which was designed to cover different materials, different types of welding process, has the potential to deal with complex products that are made up of multiple components.
