Struct FoamStack 

pub struct FoamStack {
    pub layers: Vec<FoamLayer>,
}

Multi-layer foam stack for graded energy absorption.

Fields

layers: Vec<FoamLayer>

Layers: each described by (thickness, plateau_stress, densification_strain, modulus).

Implementations

impl FoamStack

pub fn new() -> Self

Create a new empty foam stack.

pub fn add_layer(&mut self, layer: FoamLayer)

Add a layer to the stack.

pub fn total_thickness(&self) -> f64

Total thickness of the stack.

pub fn total_energy_capacity(&self) -> f64

Total maximum energy absorption per unit area [J/m²].

pub fn effective_modulus(&self) -> f64

Effective (series) modulus of the stack.

1/E_eff = sum (t_i / E_i) / sum(t_i)

pub fn num_layers(&self) -> usize

Number of layers.

Trait Implementations

impl Clone for FoamStack

fn clone(&self) -> FoamStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FoamStack

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

Formats the value using the given formatter.

impl Default for FoamStack

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FoamStack

fn eq(&self, other: &FoamStack) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
