TEST SETUP OF MATERIAL SPECIMENS AT COMPLEX CYCLIC LOADING Russian patent published in 2013 - IPC G01N3/34 

FIELD: test equipment.

SUBSTANCE: setup includes a base, specimen grips installed on it, a pusher connected to one of the grips, and a back-and-forth pusher movement actuator. The setup has a support fixed on the second grip, and a removable limit stop installed eccentrically to the grips with possibility of interaction with the support, a rotating platform installed coaxially to the grips, and a platform rotation actuator; with that, the limit stop is installed on the platform, and the support is made in the form of a disc.

EFFECT: increasing informativity of investigations by providing tests at an axial load, jointly axial and torsional loads, jointly axial and bending loads, jointly axial, bending and torsional loads with possibility of cyclic change of torsional load.
