US vehicles exported to Europe are required to pass the European Union (EU) 40% Frontal Offset Impact Test. This test uses a moving vehicle impacting a stationary offset deformable barrier (ODB). The test was developed by comparing intrusions seen in vehicle-to-vehicle offset impacts with intrusions seen in various vehicle-to-ODB impacts. To help with vehicle development to this standard, the development of an LS-DYNA (Livermore Software Technology Corporation, 1997) finite element model of the ODB was undertaken. The purpose of this research was the validation of an offset deformable barrier (ODB) model using component and sled testing and simulation of both. The material parameters developed in component punch tests and their simulations work well for the ODB model. The finite element model developed in this report results in good correlation between sled tests and simulations and this ODB model can now be used in vehicle simulations. This will allow the various ODB tests to be better modelled with better predictions of vehicle response. Thus, crashworthiness engineers may be able to design better for the ODB test. An additional finding of interest was that the honeycomb material in an ODB is somewhat unstable, because its strength is approximately two orders of magnitude greater in the primary loading direction than in the other two directions.
