}

Radiation damage material model.

Tracks displacement per atom (dpa), void swelling, embrittlement, and He bubble growth.

Fields

threshold_energy_ev: f64

Displacement threshold energy Ed (eV).

atomic_density: f64

Atomic density n (atoms/m³).

yield_strength_initial: f64

Initial yield strength σy0 (Pa).

dpa: f64

Accumulated dpa (displacement per atom).

void_fraction: f64

Void swelling fraction (dimensionless).

helium_conc_appm: f64

Helium concentration (appm).

Implementations

impl RadiationDamage

pub fn ss316l() -> Self

Creates a stainless steel 316L radiation damage model.

pub fn compute_dpa(&self, flux: f64, cross_section: f64, time: f64) -> f64

Irradiation dose in dpa from neutron flux and cross-section.

dpa = φ * σ_d * t / (n * Ed * 2).

pub fn irradiation_hardening(&self, k_hardening: f64) -> f64

Yield strength increase due to irradiation hardening.

Δσy ≈ α * μ * b * sqrt(N_d), where N_d ~ dpa density (simplified to Δσy = k * sqrt(dpa)).

pub fn yield_strength(&self, k_hardening: f64) -> f64

Total yield strength (initial + hardening).

pub fn void_swelling_rate( &self, temperature_k: f64, a_coeff: f64, b_coeff: f64, ) -> f64

Void swelling rate: dS/ddpa ≈ A * exp(-B/T) (temperature-dependent).

pub fn bubble_radius(&self, bubble_density: f64) -> f64

Helium bubble growth: r ~ (3 * C_He / (4π * n_b))^(1/3).

pub fn dbtt_shift_k(&self) -> f64

Ductile-to-brittle transition temperature shift (DBTT shift ~ 20°C/dpa).
