Struct Laminate 

pub struct Laminate {
    pub plies: Vec<(OrthotropicPly, f64)>,
}

A composite laminate described by Classical Laminate Theory (CLT).

Plies are ordered from bottom to top; mid-plane is at z = 0.

Fields

plies: Vec<(OrthotropicPly, f64)>

Plies as (ply, fiber angle in degrees).

Implementations

impl Laminate

pub fn new() -> Self

Create an empty laminate.

pub fn add_ply(&mut self, ply: OrthotropicPly, angle_deg: f64)

Append a ply with the given fiber angle.

pub fn total_thickness(&self) -> f64

Total laminate thickness h = Σ t_k.

pub fn a_matrix(&self) -> [[f64; 3]; 3]

Extensional stiffness matrix A_ij = Σ Q_bar_ij * h_k.

pub fn b_matrix(&self) -> [[f64; 3]; 3]

Coupling stiffness matrix B_ij = 0.5 * Σ Q_bar_ij * (z_k² - z_{k-1}²).

pub fn d_matrix(&self) -> [[f64; 3]; 3]

Bending stiffness matrix D_ij = (1/3) * Σ Q_bar_ij * (z_k³ - z_{k-1}³).

pub fn effective_modulus_x(&self) -> f64

Effective x-direction modulus: 1 / (A⁻¹[0][0] * h).

pub fn effective_modulus_y(&self) -> f64

Effective y-direction modulus: 1 / (A⁻¹[1][1] * h).

pub fn effective_shear_modulus(&self) -> f64

Effective in-plane shear modulus: 1 / (A⁻¹[2][2] * h).

pub fn is_symmetric(&self) -> bool

Returns true if the laminate is symmetric (B ≈ 0).
