Main functions
The creep test bench makes it possible to carry out tensile and compression creep tests on one or more standard specimens in a controlled temperature enclosure (up to +250 °C). The force is applied by an electric cylinder controlled by a strain gauge sensor. Strain measurement can be provided by digital cylinder position or a high-resolution digital camera extensometer system. This bench also allows to carry out conventional tests of traction at a fast speed.
Operating mode
The specimens are attached in “series” thanks to specific clamps. Series assembly ensures total equality of the faces applied to each specimen. After initial loading, the bench applies a controlled creep force. To carry out elongation measurements with the optical extensometer, the operator selects two optical marks on each specimen, which will be used as a reference for the length measurement. The cameras then move automatically to follow the position of each marker.
