Approach: An analytical approximation variant of plasticity and physical nonlinearity functions was presented and a numerical processing technique of experimental data was described. Results: The corresponding analytical formulas of plasticity functions and nonlinear creep were proposed with mathematically substantiated parameters. Conclusion: The theoretical and experimental results obtained were compared.}, journal = {Journal of Computer Science}, publisher = {Science Publications} }
