FIELD: physics.
SUBSTANCE: bending stress relaxation test rig for plane samples includes fixed rigid base with two loading supports, movable rigid cover with two loading support, connected to the system for travelling and measuring stress providing moving and having guide ways for forward lifting and lowering the cover in relation to the base thus maintaining sample loading symmetry. Herewith the fixed base includes interior support, while exterior support is provided on the movable cover, articulator connector of the base with the cover.
EFFECT: higher performance reliability, accuracy of relaxation stress test and reliability of relaxation dependences.
