Novel viscoelastic model for elastomers under finite strains

摘要

The general classification is suggested for models of viscoelasticmedia with finite strains, this classification is based on energeticcouples of stress and strain tensors and also on new quasi-energeticcouples of tensors introduced in this paper. Places of existingelastic and viscoelastic models for media with large deformations areindicated in this classification, and New models of viscoelasticityare suggested. Comparison of different models is conducted for theexample of polyurethanic Elastomers, advantages and shortcomings ofdifferent models are shown.
