The analysis and study of stress distribution over the whole human body and some joints by using FEM method

The biomechanics, on contrast with other areas, has a fast development in the past few years, but many of the researches are just focused on one or two parts of human body, like the knee joints or the lumbar vertebra as well as only areas closely related to medical treatments. One main reason for this fact is our body's features are very complicated, like the inhomogeneous density and the uncertainty of the reaction of our muscle and the data will even change on same person in different age. Even simple approaches to human body mechanics are missing in this area. As the first effort toward the biomechanics in this direction, idealized skeleton is used to investigate the stress distributions in various configurations that simulate human postures. Further, the analysis is extended to a few joints with real bone joints in order to show that it can help understand the stress concentrations on human body.
