Struct HallPetch 

Source 
pub struct HallPetch;
Expand description

Hall-Petch grain-boundary strengthening model.

Implementations§

Source§

impl HallPetch

Source

pub fn yield_strength(sigma_0: f64, k: f64, grain_size: f64) -> f64

Compute yield strength: σ_y = σ_0 + k / √(grain_size).

grain_size is in metres; k is the Hall-Petch slope in MPa·√m.

Source

pub fn grain_size_from_yield(sigma_y: f64, sigma_0: f64, k: f64) -> f64

Invert Hall-Petch to find required grain size for a target yield stress.
