Four different analytical methods were developed to evaluate the accuracy of a mathematical model to tit a crash test, defined by a set of experimental channels. For each evaluated curve, composed of an experimental and a simulation channel, one of these 4 methods is used and a score is computed, between 0 and 100%. A specifically developed software, ModEval, was made to perform these evaluations. Results were confirmed by an analysis of subjective model evaluations. made by 40 persons proficient in mathematical model designing.
