摘要：

A study was conducted to develop an original loading-constraining device, which was able to compensate for misalignments between testing machine rips, when tests were performed under a nominal axial load. The proposed device was extremely versatile and had several applications on different machines to perform static, high-cycle, or low-cycle fatigue tests or creep experimentation. An experimental campaign was set up to validate correct working of the new device after manufacturing it. It was important to experimentally estimate all misalignments and to measure the entity of bending components to be compared with that of nominal ones, as the fixture technique was unable to provide their full cancellation. A specimen, manufactured according to the requirements of the ASTM E606-04 standard was equipped with four electrical strain gages to address this issue.
