System for the Adaptation of Tensile Testing Machines for Executing Torsional Tests
The torsion testing system “TS-X 100” is described. It is a simple system in which tensile testing machines can readily be adapted for executing torsional tests and, in particular, for carrying out inexpensive long-time torsional tests. The system is very compact and can be installed in a testing chamber to obtain precisely defined boundary conditions. Purely torsional loadings were obtained by loading a horizontal “free suspended” specimen through opposing force couples of equal magnitude.
Depending on the loading range, an optimized system can easily be built with a stronger structure and/or longer lever arms to increase the magnitude of the applied force couples. Calibration and creep tests confirmed the suitability of the system.
