The Oasys LS-DYNA Environment launch a new Full Width Deformable Barrier Shell Model.
Arup and Oasys Ltd. have a proven track record of over 20 years of experience in barrier development using proven modelling techniques that demonstrate robustness and fidelity, including our collaboration with Cellbond.
These models have been developed to take advantage of the latest developments in the Ansys LS-DYNA code and are designed to provide robust and efficient analysis.
The Full Width Deformable Barrier (FWDB) model has been developed according to the EuroNCAP 2024’s Full Width Deformable Barrier Face specification, Version 1.0 issued in July 2024, for implementation in 2026.
The Ansys LS-DYNA model calibration has been run in MPP version of LS-DYNA R11.2.2 to ensure performance and accuracy and has been done using the test results for various quasi-static and dynamic loading conditions provided by Cellbond. This includes:
- Static tests of each honeycomb block.
- Dynamic head-on impact tests of both the individual front and rear honeycomb blocks, at 10 m/s, against a dynamometric wall.
- Dynamic pole tests of the combined front and rear honeycomb blocks, at 6.4 m/s.
Additional validation studies have been carried out using sedan and SUV vehicle tests.
