DEVICE FOR BENDING TESTING OF SAMPLES Russian patent published in 2015 - IPC G01N3/20 G01N3/32 

Abstract RU 2568333 C1

FIELD: testing equipment.

SUBSTANCE: device comprises two support elements for fixing the test sample, having the ability to rotate, and a mechanism creating a bending moment. The support elements for fixing the test sample and the mechanism creating a bending moment are made in the form of two step servodrives, the axes of which are fixedly connected through extensions with the sample which axis is perpendicular to the axes of the step servodrives. The step servodrives are made with the ability to move in the longitudinal direction of the sample by a hinge mechanism consisting of two rigid frames connected with housings of the step servodrives with the parallel rods of equal length with cylindrical pivots at their ends. The device additionally comprises a strain-gauge station connected to the computer and the resistance strain gauges mounted on the extensions.

EFFECT: opportunity to implement the kinematic or soft modes of loading the sample, while it is possible to use both the mode of lateral bending of sample and the mode of pure shear in the middle section of the sample.
