Function von_mises_stress_kernel 

Source
pub fn von_mises_stress_kernel(
    stress: &CausalTensor<f64>,
) -> Result<Stress, PhysicsError>
Expand description

Calculates Von Mises Stress from a 3x3 Stress Tensor.

$\sigma_{vm} = \sqrt{3 J_2}$ where $J_2 = \frac{1}{2} S_{ij}S_{ij}$ is the second invariant of deviatoric stress.

§Arguments

  • stress - Cauchy stress tensor (3x3).

§Returns

  • Ok(Stress) - Von Mises stress scalar.
