| Abstract: | FE models are used widely in the pedestrian safety,which has become a very important topic. Based on THUMS model,FE models of femur,tibia and fibula were improved on materials,element properties, and so on.Based on the analysis of loading characteristics of lower limb long bones on pedestrian in vehicle-to-pedestrian crashes,the FE models of long bones were fully validated against experimental results as follows:(1) quasi-static 3-point bending tests of femur,tibia,and fibula with A-P and L-M loading direct... |
