Struct PyPlasticMaterial 

pub struct PyPlasticMaterial {
    pub yield_stress: f64,
    pub hardening_modulus: f64,
    pub youngs_modulus: f64,
}

Elastoplastic material with linear isotropic hardening (von Mises).

Fields

yield_stress: f64

Initial yield stress σ_y (Pa).

hardening_modulus: f64

Isotropic hardening modulus H (Pa).

youngs_modulus: f64

Young’s modulus E (Pa) — needed for elastic predictor.

Implementations

impl PyPlasticMaterial

pub fn new( yield_stress: f64, hardening_modulus: f64, youngs_modulus: f64, ) -> Self

Create a new plastic material.

pub fn yield_function( &self, equivalent_stress: f64, accumulated_plastic_strain: f64, ) -> f64

Von Mises yield function f(σ_eq, α) = σ_eq − (σ_y + H α).

Returns a positive value when yielding; zero or negative when elastic.

pub fn current_yield_stress(&self, accumulated_plastic_strain: f64) -> f64

Current yield stress given the accumulated plastic strain.
