grains.simulation.hallpetch

grains.simulation.hallpetch(sigma_0, k, d)

Computes the yield stress from the Hall-Petch relation.

Parameters

• sigma_0 (float) – Starting stress for dislocation movement (material constant).

• k (float) – Strengthening coefficient (material constant).

• d (float or list of floats) – Diameter of the grain.

Returns

sigma_y (float or list of floats) – Yield stress.
