FIELD: testing equipment. ^ SUBSTANCE: invention refers to testing equipment, to strength tests. Plant for fatigue test of materials includes base, three plates installed on it, the first of which is intended for annular specimen to be arranged on it, and the second one is fixed on the base, flexible element intended for contacting external surface of specimen and enveloping the second and the third plates, platform for moving one of the plates, tightening device of flexible element and plate rotary drive. At that, the first plate is fixed on base, the third plate is fixed on platform; at that, platform is installed on radial guide coaxial to the first plate. ^ EFFECT: increasing amount of information by providing tests at changing sector platform of diagram of crimping load through an angle which is more than straight angle. ^ 1 dwg
