Purpose and goal
Our long term goal is that within 10 years (starting from 2014) develop at a CAE-based simulation method for crashworthiness assessment of automotive components made of structural composites. The goal is in line with the FFI objectives of reducing the environmental impact of road transport, reduced number of traffic injuries, as well as strengthening our competitiveness. Goal achievement is generally good for the project´s operational objectives. More research work need to be done to arrive at the fully fledged, efficient and accurate design methodology.
Expected results and effects
The project results have been disseminated through several conference papers and publications in international journals. We have developed four master theses and 2 Lic. Eng. in the project. Most of the project´s operational objectives have been realized at different levels. The goal of a fully fledged design tool has not been realized as of today, but the goal is reachable within the 10-year horizon. Our results and knowledge from project gives us the confidence to push the project ideas further towards efficient and robust CAE methodology for lightweight design of crashworthiness.
Planned approach and implementation
The project was carried out in four work packages, WPA-D, with damage modelling fiber/matrix level (WPA) and modeling composite laminate at the component level (WPB), testing and verification with SOTA methods (WPC), as well as dissemination and valorization of the results achieved (WPD). The project has been led by Prof. Ragnar Larsson and Associate Professor Martin Fagerström at. A total of 10 parties have participated including Chalmers - Applied Mechanics, SICOMP, VCC, Volvo AB, Autoliv, Altair Engineering, DYNAmore Nordic, Epsilon AB, Semcon AB and Escenda Engineering AB.
