Struct StandardLinearSolid 

pub struct StandardLinearSolid {
    pub e1: f64,
    pub e2: f64,
    pub eta: f64,
}

Standard Linear Solid (Zener model): springs E1, E2 and dashpot eta.

Fields

e1: f64

Equilibrium spring modulus (Pa)

e2: f64

Non-equilibrium spring modulus (Pa)

eta: f64

Dashpot viscosity eta (Pa*s)

Implementations

impl StandardLinearSolid

pub fn new(e1: f64, e2: f64, eta: f64) -> Self

Create a new Standard Linear Solid model.

pub fn relaxation_time(&self) -> f64

Time constant tau = eta/E2.

pub fn long_time_modulus(&self) -> f64

Long-time (equilibrium) modulus E_inf = E1.

pub fn short_time_modulus(&self) -> f64

Short-time (glassy) modulus E0 = E1 + E2.

pub fn relaxation_modulus(&self, t: f64) -> f64

Relaxation modulus E(t) = E1 + E2 * exp(-t/tau).

pub fn creep_compliance(&self, t: f64) -> f64

Creep compliance J(t) for the SLS model.

J(t) = 1/E1 - (E2 / (E1*(E1+E2))) * exp(-E1t / (eta(1 + E1/E2))) Simplified form: J(t) = 1/(E1+E2) + (E2/(E1*(E1+E2))) * (1 - exp(-t/tau_c)) where tau_c = eta * (E1 + E2) / (E1 * E2)
