Sled tests and simulations of offset deformable barrier

Abstract

The purpose of this research was the validation of an offset deformable barrier (ODB) model using component and sled testing and simulations of both. The material parameters developed in component punch tests and their simulations work well for the ODB model. The finite 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.
