Development of a Finite Element Model for the Pedestrian Lower Limb – Development and Validation of Bone Models –

Article of Honda R&D Technical Review Vol.13 No.2

Summary

A finite element model for the long bones of the human lower limbs that accurately reflects their anatomical structure has been developed. The average values of the material properties of the bones as well as their strain rate dependency were determined from an extensive survey of the related literature and were reflected in the model. The model has been validated against published quasi-static and dynamic 3-point bending test results, confirming that it accurately predicts the peak impact force. In addition, it was found that the strain rate dependency of the material properties has a significant effect on the accuracy of peak force prediction.
