On the theoretical interrelations between thermomechanical diagrams in tension, compression, and torsion for alloys possessing the shape memory effects

We discussed the problem of determining the theoretical interrelations in generalized thermomechanical diagrams of alloys possessing the shape memory effect (the principal stress-strain characteristics) for cases of simple loading with a preset deformation produced by tension, compression, and torsion. The results of experimental studies for checking the proposed calculation relationships are given. The experimental technique for constructing a generalized thermomechanical diagram of materials with the shape memory effect for a specified torsional deformation, with due regard for nonlinearity is also proposed.
