| 摘要 |
The present invention relates to a tension tester having a movable COD (Crack Opening Displacement) gauge, in which a displacement of a fracture formed on a test piece is measured using a tension tester, the tension tester including: a pair of jig parts installed on the tension tester to support each end of the test piece, respectively; a COD gauge which measures the displacement of the fracture; and a support part which supports the COD gauge and moves the position of the COD gauge. Accordingly, the tension tester having a movable COD gauge, which can compensate for a displacement measurement error occurring when a tension is tested, is provided. |
