This study aims to analyze the state of stresses and strains of the human proximal femoral bone using an innovative plan model. Behavior analysis for this plan model is performed experimental, using digital image correlation, and numerically, using finite element method. Mechanical load model is properly to unipodal support.

Key words: femoral human bone, plane model, digital image correlation, finite element method
