Computational material design – VTT ProperTune®
VTT ProperTune® is an Integrated Computational Materials Engineering (ICME) concept VTT has developed over the last two decades. It uses multiscale modelling for optimal material design, replacing expensive, time consuming testing and shortening time-to-market for new products by an average of 50%. It allows you to create microstructurally accurate materials and load in realistic conditions – everything digital.
Reduced product development time of mechanical components
Systematic optimisation of e.g. wear, fatigue and fracture resistance
Deeper understanding of material degradation mechanisms
VTT ProperTune® has been developed together with our industrial partners and applied to their critical components in mechanical machines and devices. It can parse massive amounts of data to virtually model and analyse material behavior on component, microstructural and atomic scales. It is used to optimise a wide variety of material properties such as lifetime endurance, wear and corrosion resistance, and fracture and fatigue durability.
VTT ProperTune® example cases
Optimization of protective coatings.
Outcome: coating solution performance improvement 40%.
Discovery and design of new steel grades.
Outcome: New steel performance improved ~200-250%.
Design processes and methods for extreme conditions.
Outcome: design accuracy improvement by 3-5 fold, able to capture product failures.
How to apply material microstructure to full-scale systems?
The core concept of Integrated Computational Materials Engineering (ICME) is to provide a systematic requirement based design approach and provide a digital framework for material discovery, design and optimization exploiting AI/ML technologies. VTT ProperTune® enables rapid development and deployment of ICME solutions. This is achieved by using multiscale modelling and material design approaches such as the Process-Structure-Properties-Performance (PSPP) principle.

How to use multiscale modelling to inspect microscale details?
Our software capabilities can be integrated to solve specific problems. With VTT ProperTune® you can digitally mimic industrial materials and accurately predict how they behave under real service conditions. Material characterization and verification process ensure that results are reliable.
Accurate modelling can be applied to a wide variety of materials and surface coatings such as:
- composite structures
- sandwich structures
Example of ICME solution for metal additive manufacturing:
VTT ProperTune® is a solution for durable products. Well begun is half done – up to 80 % of the cost and benefits of materials are based by decisions made in the design phase. Watch our video to see more.
VTT ProperTune® example cases
Lifetime of industrial crane sheave-wire rope contact.
The critical sheave to wire rope sliding-rolling contact was analysed with regard to fatigue and wear life for cast iron vs steel material pairs.
The impact wear resistance of steels, composites and elastomers were analysed and wear life optimised for severe mining conditions by multiscale material modelling and simulation.
High resolution mechanical and multiscale material models were developed for cast iron and coated components to predict wear, estimate lifetime and select optimal wear resistant materials.
