Implementations

impl MaterialProperties

pub fn steel() -> Self

Steel (structural grade).

pub fn aluminium() -> Self

Aluminium alloy 6061-T6.

pub fn concrete() -> Self

Concrete (typical structural).

pub fn rubber() -> Self

Natural rubber.

pub fn water() -> Self

Water at 20 °C.

pub fn air() -> Self

Air at 20 °C, 1 atm.

pub fn titanium() -> Self

Titanium Ti-6Al-4V.

pub fn lookup(name: &str) -> Option<Self>

Lookup a material by name (case-insensitive).

Returns None if the name is unknown.

pub fn p_wave_speed(&self) -> Option<f64>

Compute the speed of longitudinal acoustic wave (P-wave) in m/s.

Returns None for fluids where youngs_modulus == 0.

pub fn s_wave_speed(&self) -> Option<f64>

Compute the shear wave speed (S-wave) in m/s.

Returns None for fluids.

Trait Implementations

impl Clone for MaterialProperties

fn clone(&self) -> MaterialProperties

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaterialProperties

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

Formats the value using the given formatter.

impl PartialEq for MaterialProperties

fn eq(&self, other: &MaterialProperties) -> 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.
