A Review of Hyperelastic Constitutive Models for Dielectric Elastomers
PublicationDielectric elastomers are smart materials that are essential components in soft systems and structures. The core element of a dielectric elastomer is soft matter, which is mainly rubber-like and elastomeric. These soft materials show a nonlinear behaviour and have a nonlinear strain-stress curve. The best candidates for modelling the nonlinear behaviour of such materials are hyperelastic strain energy functions. Hyperelastic functions...

Does low price mean high competitiveness
PublicationWe found a strong positive relationship between Comparative Price Level Index (CPL) and Growth Competitiveness Index (GCI). We do realize that the relation we have found does not have to indicate cause and effects relationship. Competitiveness is a process which goes far beyond price level but it is detemined by lots of different elemnts. We show the GCI composition that provides a concept explaining what exactly determines competitiveness...
