<p>Disclosed is an anti-buckling device of a sheet specimen of a fatigue testing machine. The device comprises: two pressurizing plates (20) supporting both sides of a sheet specimen (10); two compressing plates (30) installed outside the pressurizing plates (20) formed around the sheet specimen (10); coil springs (40) compressed by the compressing plates (30) while being installed between the pressurizing plates (20) and the compressing plates (30), and pressurizing the side of the sheet specimen (10) which is supported by the pressurizing plates (20) by a repulsive force in accordance with the compression; a stud bolt (51) combining the pressurizing plates (20), the compressing plates (30), and the coil springs (40) by passing them; and a nut (52) adjusting a compression height of the coil springs (40) by controlling coupling while being coupled with the rear of the stud bolt (51).</p> |
