Influence of the Crystallographic and the Morphological Texture on the Elastic Properties of Fcc Crystal Aggregates

Katja Jöchen; Thomas Böhlke; Felix Fritzen

In this contribution, the prediction of the self-consistent homogenization method with regard to the effective material response of cubic crystal aggregates is analyzed and compared to results from full field simulations. The influence of the crystalline orientation distribution but also the effect of the grain shape on the macroscopic elastic response of sheet metals is especially emphasized.

Numerische Modellierung des Rissfortschrittes in porösen CVI-CFC-Verbundwerkstoffen

Romana Piat; Martin Roser; Felix Fritzen; E. Schnack

Kurzfassung Zur Beschreibung der Rissausbreitung in spröden Materialien wurde in der Literatur eine Kombination von Spannungs- und Energiekriterien vorgeschlagen. Ausgehend von der inkrementellen Energiebilanz während des Rissfortschritts wird unter Einbeziehung der dort formulierten Kriterien ein Algorithmus zur Berechnung des Rissfortschritts hergeleitet. Dieser wird zur Simulation der Rissausbreitung in porösen Materialien mit folgenden Mikrostrukturen verwendet:1. Modellierung der typischen CVI-CFC-Mikrostruktur auf Basis von Querschnittsaufnahmen einer Probe mit anschließendem Vergleich der Resultate aus der Simulation und dem 4-Punkt-Biegeversuch,2. idealisiertes, poröses Material mit kreisförmigen Poren. Ausgehend von den Resultaten der durchgeführten Untersuchungen sind Aussagen über die Rissentwicklung in einem realen Material möglich.
