Abstract: PURPOSE: A device for measuring fracture toughness of specimen is provided to achieve improved sensitivity by reducing interferences among three axes and measuring pure bending force. CONSTITUTION: A device for measuring fracture toughness of specimen, comprises a base(100); a linear step motor(200) mounted on the base so as to generate a driving force; a support(300) mounted on the linear step motor in such a manner that the support reciprocates in a horizontal direction; a vertically movable unit(400) coupled to the side of the support in such a manner that the vertically movable unit is movable in a vertical direction by the adjustment of a vernier caliper(420); a grip unit(500) having a forward grip(520) coupled to the side surface of the vertically movable unit and coupled to an end of a specimen(540) through a connection grip(560); a load cell(600) coupled to the connection grip, and which has a plurality of strain gauges attached to the outer periphery of the load cell so as to measure the force being applied to each direction of x, y and z-axes; and a load cell fixing unit(700) mounted on the base, and which supports an end of the load cell.
