Struct FailureEnvelope 

Source 
pub struct FailureEnvelope {
    pub xt: f64,
    pub xc: f64,
    pub yt: f64,
    pub yc: f64,
}
Expand description

Biaxial failure envelope for a composite material.

Represents the outer boundary of admissible stress states in the (σ11, σ22) plane using a maximum-stress interaction criterion.

Fields§

§xt: f64

Tensile strength along axis 1 [Pa].

§xc: f64

Compressive strength along axis 1 [Pa] (negative value).

§yt: f64

Tensile strength along axis 2 [Pa].

§yc: f64

Compressive strength along axis 2 [Pa] (negative value).

Implementations§

Source§

impl FailureEnvelope

Source

pub fn max_stress(xt: f64, xc: f64, yt: f64, yc: f64) -> Self

Create with explicit strengths.

Source

pub fn failure_index_biaxial(&self, sigma11: f64, sigma22: f64) -> f64

Biaxial failure index for (σ11, σ22).

Returns the maximum of the two normalised stress ratios. A value ≥ 1 indicates failure.

Source

pub fn tsai_wu_index(&self, sigma11: f64, sigma22: f64) -> f64

Tsai-Wu tensor failure index for biaxial (σ11, σ22).

FI = F1*σ11 + F2*σ22 + F11*σ11² + F22*σ22² + 2*F12*σ11*σ22

Uses F12 = -0.5*sqrt(F11*F22) (Tsai-Wu interaction term).

Source

pub fn is_inside(&self, sigma11: f64, sigma22: f64) -> bool

Check if the stress state (σ11, σ22) is inside the failure envelope.
