Function youngs_modulus 

pub fn youngs_modulus(stress: f64, strain: f64) -> Option<f64>

Computes Young’s modulus from stress and strain.

Formula: E = σ / ε.

Returns None when strain is zero, when the result is negative, or when any input or result is not finite.

Examples

use use_elasticity::youngs_modulus;

assert_eq!(youngs_modulus(100.0, 0.01), Some(10_000.0));
