2-Punkt-Wechsel-Biegeversuch zur Ermittlung der Ermüdungsbeständigkeit und der dynamischen Steifigkeit

2-point alternating flexure tests

The 2-point alternating flexure test to EN 12697-24, Annex A and EN 12697-26, Annex A is used to determine fatigue resistance and dynamic stiffness. It is the standard test method in France.

The test device has frictionless, wear-free flexure pivots, which translate the vertical piston travel into horizontal motion. Two specimens can be tested simultaneously at the same amplitude, with separate measurement of force and horizontal displacement for each specimen. A reference specimen with strain gages attached is available for calibration purposes.
