OTERO-MARTINEZ, Diana  and  OTERO-PEREIRO, Luís-L.. Constitutive models for arterial walls, description of movement and state of deformation. Ingeniería Mecánica [online]. 2014, vol.17, n.3, pp.195-204. ISSN 1815-5944.

Arterial walls are one of the soft tissues found in living organism. They are non lineal, incompressible and anisotropic. A set of constitutive models have been developed considering a hyperelastic material. Some of these models consider material isotropy but they have proved to be inadequate for modeling healthy arterial behavior. Mostly used models consider the anisotropic material due to the collagens fibers and nevertheless they have been created to describe arterial behavior can be also used for modeling different soft tissue behavior as infrarenal vena cava, intestine wall, mechanical properties of the esophagus, among others. General author have used them for modeling arterial damage.

Keywords : constitutive modelling; arterial tissue; elasticity; aortic wall; stress analysis; passive response.
