Taylor factor

The Taylor factor is a geometric factor that takes the place of the Schmid factor in polycrystalline materials . In face-centered cubic material, its value is 3.1. It is used to calculate the influence of different hardening mechanisms that influence the critical shear stress on the yield stress : ${\displaystyle M}$ ${\displaystyle \tau _{\text{krit}}}$ ${\displaystyle \sigma _{f}}$

${\displaystyle \sigma _{f}=M\cdot \tau _{\text{krit}}.}$

In this way, the generally random crystal orientation is averaged in an isotropic polycrystalline material .
