Thank you to the organizers of the Journée Scientifique et Technique 2024 on multi-scale approaches for the modeling of composite materials and structures 👏@PM, 👏Anita CATAPANO, 👏Fréderic DAU for this day which took place on February 5 at the Dassault Systèmes Paris Campus: what a great experience!
I'd also like to thank @AC for her coordination, logistical support and for promoting this type of community of exchange and sharing.
You'll find my contribution here, with a presentation on the numerical prediction of the compressive instability of carbon-epoxy composites with misaligned long fibers. The aim was to define, model and simulate compressive instability on different Representative Volume Elements (RVE) of misaligned fiber composites. The second part of the presentation focused on the application of an experimental method for characterizing the misalignment of composites [Yurgartis, 1987] on our virtual materials in order to understand whether the modeled misalignment is indeed representative, and also to understand the data obtained with this type of experimental method.
Finally, many thanks to the co-authors of the presentation @PM, Vincent Keryvin and @TL !
