ABSTRACT
Three types of tensile testing machines were employed for quasistatic, cyclic dynamic and tensile impact experiments. All machines were specifically designed for the use at synchrotron beamlines. The quasistatic machine is operated by two linear electric actuators, keeping the sample center aligned with the X-ray beam. The cyclic dynamic machine subjects the sample to a harmonic load of a frequency of roughly 1 Hz. The motion of an excenter is transfered to the clamps via an elaborate mechanism, keeping the sample center fixed with respect to the beam position. The impact tensile machine is spring-driven, stretching the sample to a predefined strain within less than 10 ms.
