Study on validation method for femur finite element model under multiple loading conditions
Acquisition of accurate and reliable constitutive parameters related to biotissue materials was beneficial to improve biological fidelity of a Finite Element(FE)model and predict impact damages more effectively.In this paper,a femur FE model was established under multiple loading conditions with diverse impact positions.Then,based on sequential response surface method and genetic algorithms,the material parameters identification was transformed to a multi-response optimization problem.Finally,the simulation results successfully coincided with force-displacement curves obtained by numerous experiments.Thus,computational accuracy and efficiency of the entire inverse calculation process were enhanced.This method was able to effectively reduce the computation time in the inverse process of material parameters.Meanwhile, the material parameters obtained by the proposed method achieved higher accuracy.
