Arup Cellbond Barrier Models

Working in collaboration, Arup and Cellbond Composites Ltd have developed a range of LS-DYNA finite element models based on the aluminium honeycomb barriers produced by Cellbond Composites Ltd.

This range of models covers all the major barriers used in the European and US Federal regulations and the main consumer test such as Euro NCAP and IIHS.

The models have been developed to take advantage of the latest developments in the LS-DYNA code and are designed to provide a robust and efficient analysis model.

Front Impact Barriers

• EEVC Offset Deformable Barrier (ODB)
• Full Width Deformable Barrier (FWDB) / Full Width Compatibility Barrier (FWCB)
• Progressive Deformable Barrier (PDB)

Side Impact Barriers

• EEVC Advanced 2000 Side Impact Barrier (Adv-2000)
• NHTSA Side Impact Barrier
• IIHS Side Impact Barrier
• AE-MDB Side Impact Barrier

Rear Impact Barriers

• NHTSA Rear Impact Barrier

Development Work These models have been developed and validated using test data obtained from: Static tests on the basic honeycomb material Dynamic tests on the basic honeycomb material Adhesive strength testing A range of full barrier crash tests Data from existing car crash tests This validation work has been carried out in both the MPP and SMP version of LS-DYNA 970 and 971 across a wide range of hardware platforms to ensure performance and accuracy.
