Abstrakt: The paper considers the description of the materials creep using the known linear models of viscoelastic bodies. The method for restoring the parameters (viscosity and elasticity) of models on the basis of the results of dynamic vibration tests is described. An example of approximation of the experimental data of the real component of the complex modulus of carbon fiber reinforced plastic by methods of regression analysis is given. With the help of restored model parameters the composite creep curves are built up. [ABSTRACT FROM AUTHOR]
