文摘
- •
A 1-dof nonlinear lumped parameters model of the intervertebral disc is proposed.
- •
The model is validated against quasi-static and dynamic experiments.
- •
A nonlinear elastic model is required to predict nonlinear phenomena similar to those seen in the experiments.
- •
The dynamic responses predicted from a linear and a nonlinear elastic viscous model are compared.
- •
The numerical parameters and the approach to use the nonlinear elastic viscous model are provided.
