Abstract: Plain deformation of thin layers between rigid blocks is considered for the case when along with elastoplastic deformations of a layer there exists its viscous deformation (creep). The model constructed is compared with the traditional model of steady creep of layers and with the model of elastoplastic deformations of layers without creep. The work was supported by Grant SS–319.2003.1 of the President of Russian Federation.

Keywords: elastoplastic deformation, creep, limit state.
