  • Title: An interface model for the periodontal ligament.
    Author: Gei M, Genna F, Bigoni D.
    Journal: J Biomech Eng; 2002 Oct; 124(5):538-46. PubMed ID: 12405597.
    Abstract:
    A nonlinear interface constitutive law is formulated for modeling the mechanical behavior of the periodontal ligament. This gives an accurate interpolation of the few available experimental results and provides a reasonably simple model for mechanical applications. The model is analyzed from the viewpoints of both mathematical consistency and effectiveness in numerical calculations. In order to demonstrate the latter, suitable two- and three-dimensional nonlinear interface finite elements have been implemented.
