CWM at the 6th Jena µCT Workshop on 23.11.2022 (University Hospital Jena)

Presentation of VEDDAC volume - our software for Digital Volume Correlation (DVC) and results of the joint research project RemaKeBone.

VEDDAC volume - is a stand-alone intuitive measurement software for the determination of 3D deformation fields and for the analysis of structural changes (e.g. cracking) inside materials based on X-ray computed tomography (CT) images.

In the RemaKeBone project (funded by the BMBF), 3D-printable bone-equivalent test materials are being developed together with partners for the realistic replication of biomechanical bone properties based on 4D deformation analysis. For the biomechanical characterization, CWM's DVC method is used on X-ray CT images with new loading technology. For this purpose, the CWM project team is developing new accelerated algorithms for DVC with even higher accuracy, which will of course then also be integrated into our DVC software VEDDAC volume.

For CWM, it is the entry into biomedicine with VEDDAC volume!

VEDDAC volume - For all who work with X-ray CT!

Now gain even more information from your CT data: By deformation analysis with the DVC software VEDDAC volume on CT data of an object before/during (in-situ) or before/after a load (ex-situ).

Regardless of whether in-situ or ex-situ: The result of the calculation shows the smallest changes in the material - and that in the sub-voxel range. VEDDAC volume is therefore an indispensable tool for early detection of material failure (e.g. later cracks or otherwise hardly visible cracks). Seeing gradients in deformation and strain - essential for the evaluation of the structure in complex structures (e.g. lightweight construction, 3D printing).

Advantages of VEDDAC volume:
  • stand-alone software - no basic module required
  • device-independent - works for all reconstructed CT data read in as image stacks
  • clear layout - easy to use
  • strain calculation from local to global - quickly done by a few mouse clicks
  • practical algorithms to choose from - even for noisy data
  • memory-optimized data processing for fluent working
  • 2D or 3D visualization - adaptable for any purpose

New! Digital image correlation software VEDDAC 7

With VEDDAC 7, even more precise and reliable surface image analyses can be performed to characterize motion, deformation and failure. VEDDAC 7 adds many new features to the proven VEDDAC 6 version. With its modern, user-friendly and intuitive program interface, VEDDAC 7 offers the user time-effective image evaluation.

microDAC® strain - With highest precision

With our video extensometer microDAC® strain it is possible to determine longitudinal and transverse strain during tensile and compression tests directly on the specimen without time-consuming specimen preparation, e.g. the application of measuring marks or the spraying on of grey value patterns.

In addition to classic applications in tensile/compression testing equipment, microDAC® strain is also optimized for use in automated strain measurement on tensile/compression loaded specimens in the scanning electron microscope (SEM) as well as for loading equipment for micro tensile specimens from Kammrath & Weiss GmbH.

microDAC® strain works with highest precision of accuracy class 0.2 according to DIN EN ISO 9513.
