Table 4 Optimal hyperelastic model of aneurysm tissue, based on the status of the aneurysm and the level of its deformation. Small deformations correspond to λ ≤ λa, medium deformations correspond to λa ≤ λ ≤ λb, large deformations correspond to λb ≤ λ.
From: On the optimal choice of a hyperelastic model of ruptured and unruptured cerebral aneurysm
Rate of deformation/Aneurysm status | Ruptured | Unruptured |
|---|---|---|
Small deformations | Neo-Hookean | Neo-Hookean |
Medium deformations | Yeoh | Neo-Hookean model |
Large deformations | Mooney-Rivlin 5 parameter model | Mooney-Rivlin 5 parameter model |
