Quantitative Validation of a Finite Element Model of a Knee-Thigh-Hip Complex of a 50^th Percentile Male

Traditionally the validation process of FE models is carried on by visually comparing two curves, respectively from an experimental test and the numerical simulation. A more rigorous way to quantitative compare two curves in the validation process would be provided by comparison metrics.

In this work the component validation of the Finite Element model of a Knee-Thigh-Hip complex was carried on by quantitatively comparing the results from the experimental tests with the corresponding numerical curves. An LSDYNA finite element model of the lower extremities was developed and the condyle, pelvis and femur and components were carefully validated using three comparison metrics. The good match.
