Purpose: The numerical simulation of creep of polymer sample was the aim of work. Design/methodology/approach: Creep investigation included polypropylene. The test stand allowed to perform the creep process during bending at the 50 MPa stress level. The numerical analysis of creep model with the uniaxial stress-strain data for concrete mathematical model was done. Findings: The investigation were helpful to the comparison of the experimental model with the mathematical model. The creep materials defined as user-coded materials can be used in numerical simulation. Research limitations/implications: The accuracy and precision of numerical and experimental research model, and difference of numerical and experimental results was a limitation of the work. Practical implications: The method and results of examinations can be used practically in numerical simulation. Originality/value: Traditional, mechanical characteristics received as a result of the investigations under tensile, torsion and compression load are insufficient to predict the behaviour of polymeric materials under the extreme usage conditions as well as during the long time. The approximation results of numerical simulations were presented. The viscoelastic properties as a function of time on the basis of empirical data were presented. The model parameters matching to experimental results.
