Axial Torsion Fatigue Testing
Materials may behave unpredictably when exposed to multiaxial loads, exhibiting different material properties. Characterizing these material properties across a wide spectrum of materials becomes very important, as there is an abundance of products that are designed to be exposed to biaxial loading during normal operating conditions.
Axial-torsion testing machines help characterize biaxial mechanical properties of materials, both in static and dynamic conditions, which helps in choosing the right materials for different applications where components are exposed to axial torsion loading profiles. This requires material research for component design and material verification stages in numerous industries and research to meet safety requirements.
Axial-Torsion applications and research areas include:
- Characterization of materials under biaxial stress loading, static or dynamic
- Cumulative damage of turbine blade components under axial-torsion loading
- Fatigue life of biomedical materials and implants
Why choose Instron?
To meet the challenges of axial-torsion testing, Instron provides a range of axial-torsion machines that cover small implants made of compliant biomaterials, composites and high-performance metals and alloys. Our servohydraulic range provides mid to high axial and torque capacities, while the ElectroPuls biaxial variants complete the range with smaller axial and torque capacities and an oil-free design, allowing labs that require a contamination free environment to conduct axial-torsion testing. Instron ElectroPuls biaxial systems also open up to testing the longevity of biomedical implants, from hip to orthopedic implants, as our systems can load specimens according to the biaxial stress profiles from actual data and measure the response of different materials and different component designs. Instron strives to provide reliable systems for companies and researchers alike to get a better understanding of materials and components under bi-axial stress profiles and offers a wide range of accessories that will suit your applications.
