Virtual Manufacturing

The “virtual prototyping & manufacturing” approach is largely accepted as a powerful, irreplaceable and common tool for process and product design to shorten development time, investigate the effects on final solutions caused by not perfectly controllable factors, reduce Time to Market costs and improve reliability of the design.


In the latest decades many software packets have been commercialised by the most important software houses, widening in this way the fields of its current use in industry, to better approach structural, static, dynamic, non linear, impact, ballistic, CFD, infusion and curing analysis.
On the other hand some other relevant questions are still under investigation:
  • the integration between different physical aspects and disciplines interesting the same components (for example, magnetism and structural performances), by adopting multi-displiplinary and multi-physics approaches;
  • the realisation of methodologies and approaches allowing the analysis of the whole life cycle of components, therefore correctly integrating different kinds of analysis, currently separately perfomed (for example; forming, structural, fatigue and crash);
  • the enlargement of the prediction power by means of a more strict relationship between macroscopic and lower scale behaviour (micro, nano ...). This latter is mandatory if a more reliable and robust approach to the failure of materials is demanded. In that respect, a scientific approach to component design based on innovative materials, such as nano-materials, composites, and MEMS, would be otherwise impracticable.
In accordance with these general needs, the technology is currently working along the following four different directions:
  • the development of multi-scale approaches in continuous mechanics, to asses several phonemena like damage;
  • the identification of robust approaches to the analysis of the micro-structural evolution of materials;
  • the development of more reliable constitutive equations for materials, allowing a more precise description of the material behaviour in different load conditions and for different plastic deformations;
  • the realisation and validation of methodological approaches able to connect different kinds of analysis having a cumulative effect on the final results (for example material manufacturing, forming and crash or fatigue performances).
