  • Failure properties and damage of cervical spine ligaments, experiments and modelling
    Trajkovski, Ana ...
    Cervical spine ligaments have an important role in providing spinal cord stability and restricting excessive movements. Therefore, it is of great importance to study mechanical properties and model ... the response of these ligaments. The aim of this study is to characterize ageing effects on failure properties and model damage of three cervical spine ligaments: the anterior and the posterior longitudinal ligament and the ligamentum flavum. A total of 46 samples of human cadaveric ligaments removed within 2448 hours after death have been tested. Uniaxial tension tests along fibre direction were performed in physiological conditions. The results showed that ageing decreased failure properties of all three ligaments (failure load, failure elongation). Furthermore, the reported non-linear response of cervical ligaments has been modelled with a combination of the previously reported hyperelastic and damage model. The model predicted a non-linear response and damage region. Material parameters are in agreement with experimental data, and the quality of agreement is represented with very low RMS error values and the values of coefficient of determination close to 1.
