Probabilistic Finite Element Analysis of Vertebrae of the Lumbar Spine Under Hyperextension Loading

The major goal of this study is to determine the stress on vertebrae subjected to hyperextension loading. In addition, probabilistic analysis was adopted in finite element analysis (FEA) to verify the parameters that affected failure. Probabilistic finite element (PFE) analysis plays an important r...
