Variants

ElasticMatrix

A general symmetric D, given as the packed upper triangle row by row: [d11, d12, d13, d22, d23, d33], with respect to the engineering-shear strain vector.

Fields

d: [f64; 6]

Orthotropic

Orthotropic plane stress. angle is the counter-clockwise angle in radians from global x to material axis 1; nu_xy is the major Poisson ratio (strain in axis 2 per strain in axis 1, loading along 1).

Fields

ex: f64

ey: f64

nu_xy: f64

g_xy: f64

angle: f64

PlaneStress

Isotropic plane stress (sigma_z = 0).

Fields

e: f64

nu: f64

PlaneStrain

Isotropic plane strain (eps_z = 0).

Fields

e: f64

nu: f64

Implementations

impl PlaneMaterial

pub fn plane_stress(e: f64, nu: f64) -> Result<Self, PlaneMaterialError>

Isotropic plane stress; e > 0 and -1 < nu < 1.

pub fn plane_strain(e: f64, nu: f64) -> Result<Self, PlaneMaterialError>

Isotropic plane strain; e > 0 and -1 < nu < 0.5.

pub fn orthotropic( ex: f64, ey: f64, nu_xy: f64, g_xy: f64, angle: f64, ) -> Result<Self, PlaneMaterialError>

Orthotropic plane stress; positive moduli and nu_xy^2 < ex / ey.

pub fn elastic_matrix(d: [f64; 6]) -> Result<Self, PlaneMaterialError>

A general symmetric positive-definite D (packed upper triangle).

pub fn validate(&self) -> Result<(), PlaneMaterialError>

Checks the constants of a value built from the variants directly.

pub fn d_matrix(&self) -> PlaneMatrix

The constitutive matrix at the committed state (constant for every elastic variant).

pub fn trial_stress_tangent( &self, strain: &PlaneVector, ) -> (PlaneVector, PlaneMatrix)

Stress and tangent at strain, always relative to the committed state.

pub fn commit(&self, strain: &PlaneVector) -> Self

The new committed material after strain converged.

pub fn is_linear(&self) -> bool

Whether the response is linear in strain and history-free (what the enhanced Quad4 requires).
