| Popis: | Neck pain is a major inhibitor affecting the performance of U.S. military personnel. Repetitive exposure to cyclic loading due to military activities over several years can lead to accumulation of fatigue damage in the cervical intervertebral disc annuli, leading to neck pain. We have developed a computational damage model based on continuum damage mechanics, to predict fatigue damage to cervical disc annuli over several years of exposure to military loading scenarios. By integrating this fatigue damage model with a finite element model of the cervical spine, we have overcome the underlying assumption of a uniform stress distribution in the annulus. The resulting element-wise damage prediction gives us insight into the location of damage initiation and pattern of fatigue damage progression in the cervical disc annulus. |
