| Abstract: | A mathematical model is proposed to describe the experimentally observed creep effect on the instantaneous elastic deformation
of physically nonlinear elastic microinhomogeneous materials. Using a structural model of the medium, it is shown that, during
unloading of a sample after creep at constant stress, the elastic strain can be both larger and smaller than the elastic strain
during loading. It is shown that calculation results for a biocomposite material are in good agreement with experimental data.
