Struct MazarsDamage 

pub struct MazarsDamage {
    pub d: f64,
    pub k: f64,
    pub at: f64,
    pub bt: f64,
    pub ac: f64,
    pub bc: f64,
}

Mazars concrete damage model (biaxial damage).

Uses positive principal strains to distinguish tension/compression.

Fields

d: f64

Current damage variable D ∈ [0, 1]

k: f64

Damage threshold (strain) k

at: f64

Tension parameter A_t

bt: f64

Tension parameter B_t

ac: f64

Compression parameter A_c

bc: f64

Compression parameter B_c

Implementations

impl MazarsDamage

pub fn new(k0: f64, at: f64, bt: f64, ac: f64, bc: f64) -> Self

Create a new Mazars damage model.

Arguments

• k0 - Initial damage threshold (strain)
• at, bt - Tension damage parameters
• ac, bc - Compression damage parameters

pub fn equivalent_strain(eps_principal: &[f64; 3]) -> f64

Equivalent strain from positive principal strains only.

ε̃ = sqrt(Σ <ε_i>+²) where x+ = max(x, 0)

pub fn update(&mut self, eps_principal: &[f64; 3])

Update damage based on principal strains.

D = at*(1 - k/ε̃)exp(-bt(ε̃-k)) + ac*(1 - k/ε̃)exp(-bc(ε̃-k))
