Abstract: A mathematical model describing the nonstationary creep of metals under complex loading is proposed. The results of numerical simulation of creep of St.304 steel in complex regimes of block multiaxial cyclic deformation are given. The numerical calculation results obtained are compared with the data of full-scale experiments. Creep is simulated in complex deformation processes accompanied by the rotation of main regions of stress, strain, and creep strain tensors.

Keywords: nonstationary creep, mathematical simulation, complex loading, creep surface, material parameters, numerical and full-scale experiments.
