摘要

The problem on creep strains analysis of the thin-walled tubular elements made of linear viscoelastic materials under uniaxial tension, pure torsion, and combined tension with torsion has been solved and experimentally approved. The solution is based on the use of a viscoelasticity model in the form of proportional deviators. Creep kernels are specified by fractional-exponential functions. Longitudinal, transverse, and shear creep strains have been calculated.
