Synchrotron & X-ray Computed Tomography (XCT) Imaging — 20kN tensile, compression and torsion rig. Top and bottom jaws contain independent high resolution rotation mechanisms allowing synchronised sample rotation. Torque can be applied by rotating one jaw further than the opposite jaw up to 100Nm loading. Tensile or compression load can be applied at the same time as torsion and loads can be applied and held while the sample is being rotated.

Sample rotation can be controlled in step or continuous mode from the associated imaging system or from the supplied control software.

Many different materials may tested at loads from -20kN to +20kN, and torsion from -100Nm to +100Nm.

An optional furnace may be fitted for sample heating to 1,000ºC.

Acquisition software is supplied for system control, real-time data display and recording of force/extension curves.

Deben 20kN Open Frame X-ray Tensile/Compression & Torsion tester

We are now able to offer an integrated tensile/compression/torsion testing solution for your µXCT application. Using tensile testing with µXCT provides a clear visual interpretation of how the properties of materials and composites change under different loading conditions. The design of these testing stages allow them to be used with high resolution micro CT systems providing a range of tensile, compression and torsion stages with forces up to 20kN. Systems are controlled from the comprehensive MICROTEST tensile stage control software giving a wide range of control functions and a live display of load versus extension and supplied with all required cabling and mounting adaptors for specific µXCT systems. Further details and pricing is available from your micro CT supplier or direct from Deben.

Currently there are two versions of the CT20kN available:
