The study of some structure behaviors may sometimes require the development of more complex material models than the traditional Hooke's law. AROBAS Technologies has an important expertise on the following complex models:

• Draped composite materials (multi-layer models);
• Charged matrix Composit materials (chaining with infection simulation software);
• Hyper elastic laws (Mooney-Rivlin type, for elastomers);
• Viscous Laws (Chaboche-Lemaître coupled type, or simple creep models like the Garofalo, Norton types).
