【 摘 要 】

Problem statement: The experimental curves for physically nonlinear deformation of aluminum alloy D-16Т have been approximated in a temperature field. 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.
