Apparatus and methods related to fatigue testing are described. For example, some embodiments may contain a terminal fixer, a terminal support, a bending machine, and a stress-strain collector, and may be used for testing fatigue properties of offshore pipes, risers and their connectors. Some embodiments may be used to apply extruding, twisting and high frequency bending to the testing sample during one testing period, so that the various fatigue properties of the testing sample can be obtained. |
