FIELD: test technology, strength testing of specimens. SUBSTANCE: device has hydraulic cylinders 4, 5, pushers 7, 8 with retainers 9, 10, platforms 11 with retainer 12, grippers 2 for specimen 3. Testing involves deforming specimen 3 by compression by two cylinders 4, 5 through pushers 7, 8 and fixing the pushers, bending the specimen by moving platform 11 and fixing by retainer 12. The retainers are switched off so as to relieve loads. The device can be used for testing tubular specimens and articles. EFFECT: widened information contact due to providing both bending and compression in a bending zone and due to separate relieving of these types of loads as well in testing tubular specimens. 1 dwg
