Three constitutive models.
| | Mechanisms | Constitutive | Description |
| | Linear elastic material (“L” case) | l = m = n = 0
Linear strain El (2) | No material or geometric nonlinearities are included | | Nonlinear elastic material (“N” case) | l ≠ m ≠ n ≠ 0
Green-Lagrange strain tensor E (1) | Both material or geometric nonlinearities are included | | Geometrically nonlinear material (“G” case) | l = m = n = 0
Green-Lagrange strain tensor E (1) | Only geometric nonlinearities are included |
