- Model reduction and changes of scale (development of explicit dynamics schemes for impact, reduced models to adapt the model to non-critical areas, etc.).
- Multi-scale dynamic models of mechanical transmissions (hybrid modular models allowing elastic deformations of gear bodies to be taken into account, models for systems with multiple gears, etc.).
- Taking account of uncertainties (deterministic models, influence of low-amplitude faults, etc.)
