Torsion Of Solid Rods with Account for the Different Resistance of the Material to Tension and Compression Under Creep

Experiments on tension and compression of solid samples cut out from a 60-mm thick plate of an Ti–Al–Sn–V alloy at a temperature of 700◦C are used to determine that this alloy possesses small anisotropy and a different resistance to tension and compression under creep. The approximations of the powe...

Description
Summary:Experiments on tension and compression of solid samples cut out from a 60-mm thick plate of an Ti–Al–Sn–V alloy at a temperature of 700◦C are used to determine that this alloy possesses small anisotropy and a different resistance to tension and compression under creep. The approximations of the power law of creep are obtained for each series of these experiments and each direction in the plate. Two models based on the transformed space of stresses are used to simulate the torsion of solid samples. The models account for the different resistance to tension and compression under creep. A series of experiments are carried out on the torsion of solid round rods cut out in the normal direction of the plate. It is shown that the computational and experimental results satisfactorily agree.
