Concrete material properties per ACI/EN standard.

Fields§

§fc: f64

Characteristic compressive strength f’c (MPa).

§ft: f64

Tensile strength ft (MPa), typically ≈ 0.1 * fc.

§ec: f64

Modulus of elasticity Ec (MPa).

§poisson: f64

Poisson’s ratio ν.

§shrinkage_strain: f64

Drying shrinkage strain ε_sh (dimensionless).

§creep_coefficient: f64

§density: f64

Density (kg/m³).

Implementations§

Source§

impl ConcreteMaterial

Source

pub fn new(fc: f64) -> Self

Create a normal-weight concrete with characteristic strength fc (MPa).

Ec is estimated by ACI 318: Ec = 4700 * sqrt(fc) (MPa).

Source

pub fn shear_modulus(&self) -> f64

Shear modulus G = Ec / (2*(1+ν)).

Source

pub fn splitting_tensile_strength(&self) -> f64

Splitting tensile strength (ACI): fct = 0.56 * sqrt(fc) MPa.

Source

pub fn ultimate_compressive_strain(&self) -> f64

Ultimate compressive strain (ACI): 0.003.

Source

pub fn modulus_of_rupture(&self) -> f64

Modulus of rupture (flexural): fr = 0.62 * sqrt(fc) MPa.
