§flory_chi: f64

Flory-Huggins parameter χ.

§temperature: f64

Temperature (K).

Implementations§

Source§

impl SwellingMaterial

Source

pub fn hydrogel() -> Self

Creates a polyacrylamide hydrogel model.

Source

pub fn hygroscopic_strain(&self, delta_rh: f64) -> f64

Hygroscopic swelling strain: ε = β_h * ΔRH.

Source

pub fn osmotic_pressure(&self, concentration: f64) -> f64

Osmotic pressure (van’t Hoff): Π = c * R * T.

Source

pub fn flory_rehner_elastic_energy(&self, swelling_ratio: f64) -> f64

Flory-Rehner elastic free energy: ΔF_el = (3/2) * ν * kT * (λ² - 1 - ln λ).

λ = swelling ratio.

Source

pub fn swelling_equilibrium_condition(&self, phi: f64) -> f64

Total swelling driving force: mixing + elastic.
