Zusammenfassung
Der Bruch von keramischen Werkstoffen geht von Fehlern aus. Diese können während der Werkstoffherstellung in Form von Poren, Rissen oder Einschlüssen oder während der Oberflächenbearbeitung entstehen. Das Versagen erfolgt durch die Ausbreitung von Rissen, die von diesen Fehlern ausgehen. Die Sprödigkeit der keramischen Werkstoffe wird durch den geringen Widerstand gegen die Rißausbreitung verursacht. Die große Streuung der mechanischen Eigenschaften ist auf die Streuung der Fehlergröße zurückzuführen.
