Resistance analysis of Tibia bone on upper, midell and terminal sections by compressive strength testing and FEM

چکیده مقاله

So far different researches have been done on human Tibia bone via various tests such as impact and torsion test and the effects of different parameters have been examined; for example age, height and sexuality on the bone resistance and strength. In this paper, the purpose is, study of Tibia bone resistance in three upper, middle and terminal parts as experimental through compressive test and finite element method. In this way that a Tibia bone has been cut to the three equal parts with the length 30 mm of three upper, middle and terminal districts, and it has been tested and assessed separately and the results have been compared with each other at the end. The results of stress-strain changes graph and force-extension graph showed that pushing resistance in the middle part was more than other parts and upper district of Tibia has less resistance than others, and Tibia bone had a fragile and crisp behavior, and it breaks quickly after passing of yield stress.
