S.P. Tymoshenko of the National Academy of Sciences of Ukraine popup.description2 The recommendations for determining creep characteristics of structural nonlinear viscoelastic polymeric materials under uniaxial and biaxial loading are developed. The recommendations are based on the nonlinear theory of the viscoelasticity which the relationship between tensors of strain and stress is given based on the hypothesis of tensor deviators proportionality, and the nonlinearity of viscoelastic properties is given by equations of the Rabotnov's equations type. The recommendations include the method for determining of nonlinear-elastic deformation region, a method for substantiating the nonlinearity of viscoelastic properties, a method for determining the parameters of heredity kernels and a method for determining creep deformations under uniaxial and complex stress states.
