This article presents the effect of contact parameters on the pattern of a passenger car crash with a round pillar. First the default parameters and then the parameters identified from a crash test were applied to the simulation. Finally, the obtained results were studied. The differences observed between the results of these two simulations are considerable, which show the sensitivity of the obtained results to the input data. Usually expert witnesses do not have other data at their disposal, except for the default data offered by the program, which can lead to inadequate accident pattern evaluation, and an approximate incident reconstruction. This shows the difficulty of accident reconstruction.
