Crucial to the interpretation of the results of any finite element analysis of a skeletal system is a test of the validity of the results and an assessment of the sensitivity of the model parameters. We have therefore developed finite element models... Read More about Assessing mechanical function of the zygomatic region in macaques: validation and sensitivity testing of finite element models.

Phillips, R., Grunchec, J. A., Ward, J. W., Fagan, M. J., Dobson, C. A., Langton, C. M., & Sisias, G. Stereo visualization of 3D trabecular bone structures produced by bone remodelling simulation

Adult human bone is constantly being renewed by a process known as remodelling. For cancellous bone this renewal process occurs at the interface between bone and marrow where bone is depleted by osteoclasts and rebuilt by osteoblasts. This remodellin...
