Most of the carmakers show a clear interest in the replacement of metal by continuous carbon fiber composites to reach their targets in terms of lightweighting while keeping or improving the global performances of each new vehicle. Thanks to its complex heterogeneous microstructure this material provides a better ratio mass/strength than metal for this purpose, especially for crash objectives. One of the challenge to fully integrate this advanced material into the next vehicles structures is to be able to accurately predict its post-failure behavior in order to define the best optimized design. An efficient behavior prediction for crash performances is reached when the simulation is able to capture the correct dissipated energy and the associated damage not only globally but also locally.
