In-situ CT allows taking several consecutive images to dynamically track the behavior of the object while it is subjected to an external load - for example, a mechanical, thermal, or corrosive load.
We are able to subject material samples to a series of complementary in-situ investigations. These include tensile, compression and flexural tests, which can be performed in a temperature window between -20 and +160 °C and either linearly or cyclically.
In contrast to commonly practiced tensile or compression tests, flexure tests involve a complex loading case with simultaneous influence of tensile and compressive forces, through which more extensive information about the failure mechanisms can be acquired.
We have the capability to perform 4-point flexure tests at multiple scales:
- Small specimens (approx. 24 x 10 mm) at high resolution (< 10 µm).
- Larger, practical specimens (up to 150 mm x 25 mm) in accordance with DIN EN ISO 14125
Comparative testing at several scales makes it possible to visualize influences of the limited specimen dimensions for high-resolution scans and thus include them in the evaluation of failure processes. The modular design of the in-situ flexure test also allows adaptation to specimen geometries that deviate from DIN EN ISO 14125.
