| Abstract: | Objective To analyze stress distribution of proximal femur under normal double legs standing position with three dimensional finite element analysis so as to verify the correspondent relationship between stress and structure in the position. Methods After building three dimensional finite element model of the proximal femur of normal person, border condition was determined and add loads, then calculate and illustrate stress distribution of proximal femur by using the software of three dimensional finite element analysis. Results It was found that the stress distribution of the proximal femur is reasonable and the correspondent relationship between stress and structure is verified as expected. Conclusion Three dimensional finite element analysis is a kind of convenient and practicable method to be used as the confirmation and supplement of experimental biomechanics study of human being. |
