Abstract
An approximate analysis of creep stresses in a Bridgman notched bar is given. In the case of strongly nonlinear creep, the rigid-creep model can be used. Both tension and combined tension-torsion are considered. A triaxial tension takes place in the central part of the bar. The maximal axial stress decreases with increasing twist and increasing creep index. At moderate torque, the influence of torsion on the stress state in the central part of the bar is relatively insignificant.
