Motion analysis study on sensitivity of finite element model of the cervical spine to geometry
Zafarparandeh, Iman; Erbulut, Deniz Ufuk; Özer, Ali Fahir (SAGE Publishing Ltd, 2016)Numerous finite element models of the cervical spine have been proposed, with exact geometry or with symmetric approximation in the geometry. However, few researches have investigated the sensitivity of predicted motion ...
