Wear modeling and material testing of elastomers

Novel modeling methods can gradually be applied in a modeling assisted material design process to couple material nano-microstructure and composition to performance of a component. Moreover, multiscale material modelling is the only scientifically sound way to predict the lifetime in materials that meet high wear, which for a wear problem can contain finite and discrete element means enabling computational analysis of material behavior in process environments. Nevertheless, modeling of elastomer behavior at that accuracy is a very demanding task. Modeling relies on experimental testing of actual rubber material mechanical properties and failure and wear models on material behaviour under impact type surface attacks and erosive environments. VTT has developed and offers solid experience and advanced computational tools, VTT ProperTuneT, to tackle even the most complex material design challenges.
