Novel viscoelastic models for elastomers under finite strains

The general classification is suggested for models of viscoelastic media with finite strains, this classification is based on energetic couples of stress and strain tensors and also on new quasi-energetic couples of tensors introduced in this paper. Places of existing elastic and viscoelastic models for media with large deformations are indicated in this classification, and new models of viscoelasticity are suggested. Comparison of different models is conducted for the example of polyurethanic elastomers, advantages and shortcomings of different models are shown.
