In the forward problem, a finite element approximation for a three-dimensional dental implant-bone model is first built. A RB approximation is then established by using a proper orthogonal decomposition - Greedy algorithm and the Galerkin projection to enable extremely fast and reliable computation of displacement responses for a range of material properties. In the inverse analysis, the RB approximation for the dental implant-bone model are incorporated in the Levenberg-Marquardt-Fletcher algorithm to enable rapid identification of the unknown material properties. Numerical results are presented to demonstrate the efficiency and robustness of the proposed method. © 2013 Taylor & Francis.||Source Title:||Inverse Problems in Science and Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/61198||ISSN:||17415977||DOI:||10.1080/17415977.2012.757315|
