Struct PlyState 

pub struct PlyState {
    pub angle_deg: f64,
    pub thickness: f64,
    pub q_matrix: [f64; 4],
    pub ff_failed: bool,
    pub iff_failed: bool,
    pub degradation: f64,
}

State of a single ply in a laminate.

Fields

angle_deg: f64

Ply angle (degrees from laminate x-axis).

thickness: f64

Ply thickness (m).

q_matrix: [f64; 4]

In-plane stiffness matrix Q [Q11, Q22, Q12, Q66] (Pa).

ff_failed: bool

Whether fiber fracture has occurred.

iff_failed: bool

Whether inter-fiber fracture has occurred.

degradation: f64

Degradation factor applied (0..1, 1 = no degradation).

Implementations

impl PlyState

pub fn new( angle_deg: f64, thickness: f64, e1: f64, e2: f64, nu12: f64, g12: f64, ) -> Self

Constructs a PlyState from elastic constants.

E₁, E₂ (Pa), ν₁₂, G₁₂ (Pa).

pub fn apply_degradation(&mut self, rule: DegradationRule, ff: bool, iff: bool)

Applies stiffness degradation according to rule and failure mode.

pub fn q11(&self) -> f64

Returns the effective Q₁₁ after degradation.

pub fn q22(&self) -> f64

Returns the effective Q₂₂ after degradation.

pub fn q12(&self) -> f64

Returns the effective Q₁₂ after degradation.

pub fn q66(&self) -> f64

Returns the effective Q₆₆ after degradation.
