Axial-Torsion Testing | Biaxial Testing Systems
Many materials and components are subjected to multi-axial stress-strain fields either during installation or actual use. Multi-axial stress fields are generated by an axial-torsion testing machine capable of imparting uniaxial tension/compression and torsional forces. Axial-torsion tests involve simultaneous axial-torsional loading which may be monotonic or cyclic in nature. Several axial-torsion test examples are measuring the adhesive properties of biopolymers; determining the mechanical properties of bone screws according to ASTM F543; or determining the durability of thin walled tubing. Many axial-torsion tests are quite demanding because the amplitudes and frequencies of each axis may vary greatly.
ADMET offers a line of static and dynamic, floor standing and table-top axial-torsion test systems which come equipped with our biaxial version of the MTESTQuattro Materials Testing System.
An example of an axial-torsion testing standard is ASTM F543 – Test Methods for Metallic Medical Bone Screws
