Abstract

The purpose of this study is to optimize the artificial lumbar spine with the most lightweight three - dimensional porous structure while satisfying the safety factor of 3. We have introduced representative volumes to proceed with a local analysis and studied the maximum porosity distribution that meets allowable stress. The maximum porosity was studied at 12 points and the intermediate values were predicted based on this points. If the lumbar spine is designed according to this predicted results, the optimal design will be achieved.
