11.3.2 f inite e lement m odel V alidation
As shown in Table 11.1, there have been numerous recent publications on FE models of the pelvis,
but only a few of them were experimentally validated. Model validation is extremely necessary in
biomechanical research for gauging the accuracy of predictions. There are several methods for vali-
dating an FE model, such as in vivo and in vitro experiments and model-model validation (using a
validated model to validate another new model).
