Compact Tension Fixtures for Fracture Mechanics
The Instron 2750 Series fracture mechanics grips are suited to static and dynamic testing of compact tension specimens in accordance with the following standards:
- ASTM E 399
- ASTM E 647
- ASTM E 813
- ASTM E1 290
- BS 7448
操作原理
The upper and lower grips are identical, and attach to the specimen by means of a clevis pin arrangement. The 10 kN and 50 kN grips require a set of adapters which provide for attachment to the load cell or actuator (via an appropriate attachment kit).Clevis pins are provided with spring clips or covers to prevent them from being shaken loose during testing.適用範囲
- Type of loading: Static or dynamic (tension/tension)
- Specimen material: Typically metallics
- Specimen geometries: Compact tension (6.5 mm, 13 mm, 25 mm and 50 mm thickness)
