Struct GradientEnhancedDamage 

pub struct GradientEnhancedDamage {
    pub c: f64,
}

Gradient-enhanced damage regularization.

Implicit gradient formulation: ε̄ - l_c² ∇²ε̄ = ε

This is a simplified 1D discretization for a single bar element.

Fields

c: f64

Characteristic length squared c = l_c².

Implementations

impl GradientEnhancedDamage

pub fn new(lc: f64) -> Self

Create gradient-enhanced regularization from characteristic length l_c.

pub fn solve_1d(&self, local_strains: &[f64], element_size: f64) -> Vec<f64>

Solve the implicit gradient equation in 1D for a uniform bar.

Discretized with finite differences: ε̄_i - c*(ε̄_{i-1} - 2*ε̄_i + ε̄_{i+1})/h² = ε_i

Uses Thomas algorithm (tridiagonal solver).
