TEST SETUP OF SPECIMEN FROM MATERIAL WITH SHAPE MEMORY, AT COMPLEX STRESS CONDITION Russian patent published in 2013 - IPC G01N3/18 

FIELD: machine building.

SUBSTANCE: setup includes a housing, an assembly for cyclic heating and cooling of a specimen, upper and lower specimen holders, an axial loading assembly, a static torsion loading assembly, which is rigidly attached to a two-arm lever and upper holder, and a deformation metre. Setup includes cyclic torsion loading assembly made in the form of a vibrator connected through a strain-gauge assembly to lower catch and consisting of a lever, one end of which is connected to shaft with unbalanced mass, connected to an electric motor and installed in the housing with possibility of being rotated, and a spring is fixed on the other end. Strain-gauge assembly consists of a hollow cylinder with cooling liquid supply and discharge connection pipes and resistance strain gauges. Static torsion loading assembly consists of a shaft rigidly attached to a bar system of upper holder. Housing of torsion loading assembly is rigidly attached to the setup housing, and deformation metre is made in the form of a dynamometer with wire resistance strain gauges on its surface.

EFFECT: possible testing of the specimen from material with shape memory at combined action on the specimen of cyclic heating and cooling, axial load and torsion load, and additionally, with simultaneous application of forces of cyclically oscillating movements.
