Rimac Automobili’s main challenge has been to design a monocoque as a single carbon fiber part with an unprecedented size. Hence, in the development of the monocoque, the main topic to manage was the material, a lightweight, carbon fiber reinforced with epoxy resin. As this carbon fiber is an orthotropic and brittle material, its representation in a finite element (FE) material card is very difficult. To meet this challenge the company introduced Altair HyperWorks™ into their development process.
