Der Taylor-Faktor M {\displaystyle M} ist ein geometrischer Faktor, der in polykristallinen Materialien an die Stelle des Schmid-Faktors tritt. In kubisch flΓ€chenzentriertem Material betrΓ€gt sein Wert 3,1. Er wird verwendet, um den Einfluss verschiedener Verfestigungsmechanismen, die die kritische Schubspannung Ο Ο krit {\displaystyle \tau _{\text{krit}}} beeinflussen, auf die FlieΓspannung Ο Ο f {\displaystyle \sigma _{f}} zu berechnen:
Ο Ο f = M β
β
Ο Ο krit . {\displaystyle \sigma _{f}=M\cdot \tau _{\text{krit}}.}
Auf diese Weise wird in einem isotropen polykristallinen Material ΓΌber die im Allgemeinen regellose Kristallorientierung gemittelt.
