Abstract

The main objective of the project is to perform a comparative study of the dynamic performance of various types of test rigs for crashworthiness applications and to help calibrate these devices using the Joint Research Centre (JRC) Large Scale Hopkinson Bar as a reference. The results presented in this report are those from 2 rounds of testing conducted at 14 European laboratories. Tests were performed on an extruded triggered aluminium column and comparisons made between the results of different tests regarding the first peak load, the mean crushing load, the energy dissipated by the column and the energy lost into the foundation of the rigs. These comparisons will help to develop calibration procedures for a given crash rig. Another advantage of the present international project is to demonstrate an inevitable scatter of results between various laboratories. Results of static and dynamic tests on the material characteristics conducted by 3 laboratories are presented. A parallel numerical simulation was carried out by 6 laboratories. Results of these calculations are compared in the report. An experimental validation was also performed.
