Numerical simulations demonstrated that cross-section deplanation occurs during the torsion of circular rods cut in the longitudinal direction of the plate made of an alloy with the reduced resistance to creep in the direction under $45^\circ$ to the normal direction of the plate. In experiments, this is visually confirmed by the appearance of spiral lines on the samples. The results of calculation reveal insignificant influence of the reduced resistance to creep in the transverse shear direction on the process of torsion of the plates. However, the process of torsion is accelerated for ribbed plates with increased thickness and rib height compared to the calculation in isotropic formulation.
Keywords: creep, bending, ribbed plate, transversely isotropic alloy, shear stress.
