Struct ProgressiveDamage 

pub struct ProgressiveDamage {
    pub plies: Vec<PlyState>,
    pub rule: DegradationRule,
    pub strengths: Vec<PlyStrength>,
    pub fpf_load: f64,
    pub lpf_load: f64,
}

Progressive damage analysis of a composite laminate.

Performs ply-by-ply failure analysis using the chosen criterion, applies stiffness degradation, and tracks first-ply failure (FPF) and last-ply failure (LPF) loads.

Fields

plies: Vec<PlyState>

Ordered list of ply states.

rule: DegradationRule

Degradation rule applied when a ply fails.

strengths: Vec<PlyStrength>

Strength per ply.

fpf_load: f64

Applied load multiplier at FPF (0 = not yet reached).

lpf_load: f64

Applied load multiplier at LPF (0 = not yet reached).

Implementations

impl ProgressiveDamage

pub fn new( plies: Vec<PlyState>, strengths: Vec<PlyStrength>, rule: DegradationRule, ) -> Self

Constructs a ProgressiveDamage model from ply states, strengths, and rule.

pub fn n_intact(&self) -> usize

Returns the number of intact (unfailed) plies.

pub fn all_failed(&self) -> bool

Returns true if all plies have failed (last-ply failure).

pub fn a_matrix(&self) -> [f64; 6]

Computes the laminate ABD A-matrix (membrane stiffness, 3×3) using CLT.

Returns [A11, A22, A12, A16, A26, A66] (Pa·m).

pub fn progressive_failure_sweep( &mut self, applied_load: [f64; 3], n_steps: usize, ) -> f64

Performs a progressive failure sweep at a given load vector [N₁, N₂, N₆] (Pa·m).

Returns the load factor at first-ply failure and updates ply states.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for ProgressiveDamage

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