Comparison of crash tests and simulations for various vehicle restraint systems

The use of computational mechanics methods is now largely adopted in the field of Road Side Safety. They are certainly interesting in the context a product development. However, the application of these methods in the certification process raises number of issues, addressed, among others, within the EU CEN TC226/WG1/TG1/CM-E, where some of the authors participate. This paper presents some crash test results and their related simulations, and aims to cover a wide panel of devices, different both in the architecture of the devices and in the outcome of the crash test carried out for certification. After a brief presentation of the failure modes observed, we discuss different validation criteria.
