FLEX-PLI-GTR v2.0 Release

March 23, 2012 - Humanetics Innovative Solutions is pleased to announce that the FLEX-PLI-GTR FE Consortium group has released version 2.0 of the FLEX-PLI-GTR LS-DYNA, PAM-CRASH, RADIOSS and ABAQUS models.

In November 2008, a consortium was kicked of aiming to develop high quality FE models of the FLEX- PLI-GTR. The consortium consisted of 10 OEMs, BASt and Humanetics. In January 2012, the group released version 2.0 which meets the targets that were set at the start of the project.
Since 2008, eight consortium meetings were held which were consistently well participated by the OEM end-users and the developers of the models. The meetings served to steer the project and helped to bring the model quality to the current high level. The models have been validated against a well-controlled experimental data set consisting of material, component and full leg tests which were defined by the consortium group and generated specifically for model development purposes. The 10 full leg load cases cover a wide range of load levels, and the models shows excellent overall correlation. Almost all the injury channels (MCL and tibia moment) show less than 15% peak error for these full leg load cases. With the current project finalized, the group wishes to extend the project as soon as the FLEX-PLI- GTR hardware and corresponding certification conditions are frozen and approved by the committees involved. This should guarantee that the model represents the finalized hardware. A second future goal is to validate the models against new test data that is generated with several hardware legs at different test labs, in order to better understand the potential variability.
Mr. Robert Kant from Humanetics and co-chairman of the consortium states: “Developing the FLEX-PLI-GTR models within a consortium was a new and great experience for the Humanetics team. Humanetics is developer and manufacturer of numerical and physical tools. Adding the end-user knowledge and co-operating intensively with the industry gives great benefits to all parties especially for new complex test-tools that are entering new test procedures. Humanetics would hereby like to thank all consortium members for their valuable contributions and is looking forward to further cooperation.”
Mr. Bastian Keding, Porsche AG engineer and co-chairman of the group states: "The Flex-PLI-GTR-Model version 2.0 shows good correlation compared to our validation test program in all 4 codes. I would like to thank all consortium members including the Humanetics team for their activity and creative participation. The consortium would like to continue the work on the CAE model after the hardware design is finalized in all conditions. The goal will be to further reduce differences between test and simulation on vehicle level by setting-up new validation load cases especially based on new experiences on vehicle level."
