Analysis of stress and displacements of phalanx bone with the finite element method.

In this paper analyze of phalanx bone supposed at compression, torsion and bending is made. We know that the bones are one of the most important natural composite materials. The finite element method offers the possibility for the study of the stress and the displacements which appears in different solicitations cases. We realized that the most solicited parts of the bone which will be the next broken parts, so the fracture are the once from the meeting of the bone's body with its hand. The observations made by studying 74 cases of fractures caused by torsion and compression and also made by the testing of 23 phalanx bones confirm these conclusions.
