The influence of the modulus–density relationship and the material mapping method on the simulated mechanical response of the proximal femur in side-ways fall loading configuration

The influence of the modulus–density relationship and the material mapping method on the simulated mechanical response of the proximal femur in side-ways fall loading configuration

Highlights • We model 16 human femurs tested in a side-ways fall loading configuration. • We use 10 modulus density relationships and 5 material mapping methods. • Validation outcome is highly sensitive to both input variables.
