Defect formation models for LPBF.

Fields

relative_density: f64

Measured relative density (0–1).

energy_density: f64

Volumetric energy density (J/m³).

lof_threshold: f64

Threshold energy density below which lack-of-fusion pores form (J/m³).

keyhole_threshold: f64

Threshold energy density above which keyhole pores form (J/m³).

uts: f64

Ultimate tensile strength of the matrix material (Pa).

fracture_toughness: f64

Fracture toughness of the matrix (Pa·√m).

defect_size: f64

Characteristic defect size (m) — used for cracking criterion.

Implementations

impl DefectModels

pub fn new( relative_density: f64, energy_density: f64, lof_threshold: f64, keyhole_threshold: f64, uts: f64, fracture_toughness: f64, defect_size: f64, ) -> Self

Construct a DefectModels struct.

pub fn has_lack_of_fusion(&self) -> bool

True if the energy density is below the lack-of-fusion threshold.

pub fn has_keyhole_porosity(&self) -> bool

True if the energy density is above the keyhole threshold.

pub fn porosity_fraction(&self) -> f64

Porosity fraction estimated from the relative density.

pub fn cracking_criterion(&self) -> bool

Cracking criterion using a stress-intensity-factor approach.

Returns true when the mode-I SIF exceeds the fracture toughness: K_I = σ_UTS · √(π · a) > K_IC.

pub fn in_process_window(&self) -> bool

Quality flag: process is in the “sweet spot” (no LOF, no keyhole).

Trait Implementations

impl Clone for DefectModels

fn clone(&self) -> DefectModels

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DefectModels

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
