Abstract

Ein dreidimensionales FEM-basiertes Simulationsmodell zur virtuellen Prüfung von hybriden Clinchverbindungen aus Faser-Kunststoff/Metall-Verbunden wurde entwickelt und in der kommerziellen Finite-Elemente-Software Abaqus aufgebaut. Das Simulationsmodell besteht aus zwei Berechnungsmodulen: Einem zur Simulation des hybriden Clinchprozesses, und einem weiteren zur numerischen Vorhersage der Festigkeit der hybriden Clinchverbindung. Zunächst werden experimentelle Ergebnisse zum hybriden Clinchen der Faser-Kunststoff/Metall-Verbunde (EN AW-5754 / PA6GF30) vorgestellt. Anschließend wird das entwickelte Berechnungsmodell detailliert beschrieben, wobei hier insbesondere auf die konstitutiven Materialmodelle, die für die einzelnen Fügeparameter in Abaqus implementiert worden sind, sowie auf das Simulationsverfahren eingegangen wird. Nach Berechnung des hybriden Clinchprozesses und erfolgreicher Modellvalidierung wird das Berechnungsmodul zur virtuellen Prüfung der Verbindungsfestigkeit angewandt. Durch den Vergleich der Simulationsergebnisse mit den experimentellen Daten wird die Anwendbarkeit und Genauigkeit des hier entwickelten virtuellen Prüfstands aufgezeigt
