Implementations§

impl Material

pub fn compute_stress( &self, f: &Matrix<f64, Const<3>, Const<3>, ArrayStorage<f64, 3, 3>>, j: f64, ) -> Matrix<f64, Const<3>, Const<3>, ArrayStorage<f64, 3, 3>>

Compute first Piola-Kirchhoff stress from deformation gradient.

Returns stress tensor P = ∂ψ/∂F where ψ is the strain energy density.
