    pub yield_strength_mpa: Fix128,

    pub hardening_type: HardeningType,
    pub youngs_modulus_mpa: Fix128,
}

Elastoplastic constitutive model parameters.

Fields

yield_strength_mpa: Fix128

Initial yield stress σ_y0 (MPa).

hardening_modulus_mpa: Fix128

Linear hardening modulus H (MPa). Slope of the σ vs ε_p curve.

Typical polymer values: PLA H ≈ 200 MPa, ABS H ≈ 150 MPa. Metals: mild steel H ≈ 1500 MPa, aluminium H ≈ 500 MPa.

hardening_type: HardeningType

Hardening law.

youngs_modulus_mpa: Fix128

Young’s modulus (MPa) for elastic strain accumulation.

Implementations

impl PlasticModel

pub fn from_fdm_material(m: &MaterialProperties) -> Self

Construct from an isotropic material. Defaults to isotropic hardening with H = 0.05 · E (typical elastic-plastic ratio for polymers).

pub const fn with_hardening(self, ht: HardeningType) -> Self

Override the hardening law, leaving every other parameter unchanged.

Install the result on crate::structural_solver::StructuralSolver::plastic_model to run a load history under kinematic or combined hardening (the solver’s own default is the isotropic Self::from_fdm_material).
