impl MaterialMixture

Source

pub fn voigt_modulus(e1: f64, e2: f64, phi: f64) -> f64

Linear (isostrain / Voigt) rule for Young’s modulus.

E_V = φ·E₂ + (1-φ)·E₁

Source

pub fn reuss_modulus(e1: f64, e2: f64, phi: f64) -> f64

Isostress (Reuss) rule for Young’s modulus.

1/E_R = φ/E₂ + (1-φ)/E₁

Source

pub fn hill_modulus(e1: f64, e2: f64, phi: f64) -> f64

Hill average: E_H = (E_V + E_R) / 2.

Source

pub fn voigt_conductivity(k1: f64, k2: f64, phi: f64) -> f64

Voigt (linear) rule for thermal conductivity.

Source

pub fn hashin_shtrikman_upper_bulk( k1: f64, k2: f64, g1: f64, _g2: f64, phi: f64, ) -> f64

Hashin-Shtrikman upper bound for bulk modulus.

§Arguments

α_eff = (φ·α₂·K₂ + (1-φ)·α₁·K₁) / (φ·K₂ + (1-φ)·K₁)

where K_i are bulk moduli of the individual phases.
