Advantages of grips employing deflection
- With pneumatic end clamping the gripping force remains constant, allowing high specimen throughput.
- Automatic centering of specimens via guide grooves in the load reduction curve.
- No transverse forces are transmitted to the load cell via the specimen grips.
- The symmetrical weight distribution allows the center of gravity of the grips to be near the tensile axis.
