1. Modelling of non-elastic effects of elastomers

   The topic is motivated by properties of elastomers and composites used in production of tyres. Rubber and other elastomers show large elastic strains the computational modelling of which exploits hyperelastic constitutive models. However, under extremely large strains (up to hundreds percents) also non-elastic effects occur (Mullins’effect, plasticity, viscoelasticity) and cause significant differences between models and reality as well as secondary anisotropy of the elastomer properties. Recently constitutive models are broadly developed for description of these effects. The topic aims at anisotropic behaviour of elastomers caused by Mullins’effect, implementation and exploitation of the respective constitutive models with their eventual application at fibre composites with elastomer matrix (rubber reinforced with textile and other fibres).
