Description

 Dependence between kernels of intensity of creep and kernels of volume creep at a difficult tension and kernels of longitudinal and transversal creep under the uniaxial tension have been established. The creep and relaxation kernels are given by the fractional-exponential functions. The problem of the stress relaxation analysis of nonlinear-viscoelastic thin-walled tubular elements under combined tension with torsion is solved.
