TENSILE TEST DEVICE AND TENSILE TEST METHOD

摘要

PROBLEM TO BE SOLVED: To provide a tensile test device which can measure a superelasticity property and a viscoelasticity property simultaneously.SOLUTION: A tensile test device 100 comprises: an upper side chuck 21/a lower side chuck 22 by which both ends of a test piece T is held; a rod 41 which can be connected with the lower side chuck 22; an approach mechanism 30 which is interposed between the rod 41 and the lower side chuck 22; and a linear motor 42 which moves the rod 41 in a prescribed direction. The approach mechanism 30 comprises: a guide 35 which is connected with the lower side chuck 22 and can move in a direction of movement of the rod 41; a hook part 37 which is arranged in the guide 35; and a part 43 to be hooked which is arranged in the rod 41 capable of being hooked to the hook part 37. The guide 35 is relatively movable with respect to the rod 41. The part 43 to be hooked is hooked to the hook part 37 so that the guide 35 and the rod 41 are integrally movable. A stop auxiliary mechanism 60 is installed at a terminal end of a moving range in a tension direction of the lower side chuck 22.SELECTED DRAWING: Figure 1
