Module tensor 

Stress and strain tensors for continuum mechanics.

Provides Cauchy stress tensor and infinitesimal strain tensor representations using 3×3 symmetric matrices from nalgebra.

Structs

StrainTensor

Infinitesimal strain tensor — symmetric 3×3 tensor for small deformations. ε_ij = 0.5 * (∂u_i/∂x_j + ∂u_j/∂x_i)

StressTensor

Cauchy stress tensor — a symmetric 3×3 tensor representing the state of stress at a point.
