Struct SlipSystem 

pub struct SlipSystem {
    pub slip_direction: [f64; 3],
    pub slip_normal: [f64; 3],
    pub schmid_factor: f64,
}

Single crystallographic slip system with a Schmid factor.

A slip system is defined by a slip direction d and a slip plane normal n. The Schmid factor m = cos(φ)·cos(λ) is the projection of the loading axis onto the slip system.

Fields

slip_direction: [f64; 3]

Unit slip direction (crystal frame).

slip_normal: [f64; 3]

Unit slip plane normal (crystal frame).

schmid_factor: f64

Schmid factor for uniaxial loading along e₁ = [1,0,0].

Implementations

impl SlipSystem

pub fn new(direction: [f64; 3], normal: [f64; 3]) -> Self

Create a slip system from a direction and plane normal.

Both vectors are normalised internally; the Schmid factor is computed for a loading axis along e₁ = [1,0,0].

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

Schmid tensor P = (d ⊗ n + n ⊗ d) / 2 (symmetrised).

pub fn resolved_shear_stress(&self, cauchy_stress: &[[f64; 3]; 3]) -> f64

Resolved shear stress τ = σ : P (double contraction with Cauchy stress).

Trait Implementations

impl Clone for SlipSystem

fn clone(&self) -> SlipSystem

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

Performs copy-assignment from source.

impl Debug for SlipSystem

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

Formats the value using the given formatter.
