  Background: Currently, crash dummies and mathematical model of human were mainly developed based on the European human statistical data.The prediction accuracy for Chinese was remained to be studied.Objective: The current study aims to explore the modeling methods of Chinese 50th percentile human body.Method and material: Geometry model based on the CT data from a Chinese male volunteer close to the anthropometry of 50th percentile was scaled to the 50th percentile male model according to Chinese human body statistics.The rate dependent and different property in compression and tension of cortical bone was simulated with Ls-Dyna material model.Trabecular of femoral head was divided into three parts with different material parameters to imitate the regional variations of it.The femoral head was also validated by compression loading.Results: The result shows that the proposed model has higher accuracy and biological fidelity.Conclusions : It is believed that the proposed method, modeling accuracy, geometry scaling and fully verified could be used to develop accurate 50th Chinese human body Finite Element (FE) model.
