The behavior of an automotive dashboard has been evaluated using mathematical FEM models in combination with explicit structural codes in accordance with EEC homologation test 78/632. The test simulates the impact of the human head against the dashboard which can occur during a front crash. The simulation of the impact phenomenon in the basic dashboard configuration was examined as related to a series of design variants elaborated to eliminate critical areas. Variations in the stresses were determined in the component in reference to the basic model. An indispensable premise to achieving these results was the execution of FEM process simulations aimed at obtaining the actual distribution of the mechanical strength properties, which were weighted according to the localized influence of different temperatures and flow stresses during injection.
