Torsion testing involves twisting a material or component to determine its behavior under rotational stress. This is critical for assessing the durability and performance of fasteners, drive shafts, couplings, and medical devices such as bone screws and spinal implants.
Testing Modalities & Precision Control
TRI torsion systems provide high-resolution data for rotational performance:
- Pure Torsion: Measuring torque vs. angular displacement to determine shear modulus and torsional yield strength.
- Axial-Torsional: Simultaneous loading to simulate real-world multi-axis stress states.
- Fatigue Torsion: Evaluating the endurance of components subjected to repeated rotational cycles.
Hardware Integration
Our torsion systems include the Newton Controller, providing synchronized high-speed data acquisition.
- High-Resolution Tracking: Precise measurement of torque and angle of twist.
- Modular Mounting: TRI torsion systems follow standard industrial mounting logic to ensure fixture compatibility. For axial-torsional setups, the system maintains compatibility with our standard interface logic.
- Versatile Fixturing: We offer a wide range of chucks, collets, and specialized grips to secure everything from fine wires to industrial fasteners.
Common Standards Supported
TRI equipment is engineered to execute protocols in accordance with international standards, including ASTM F543 (Medical Bone Screws), ASTM A938 (Wire Torsion), and ISO 7800.
