  - <jats:p>In lightweight design, clinching is a cost-efficient solution as the joint
    is created through localized cold-forming of the joining parts. A clinch point’s
    quality is usually assessed using ex-situ destructive testing methods. These,
    however, are unable to detect phenomena immediately during the joining process.
    For instance, elastic deformations reverse and cracks close after unloading. In-situ
    methods such as the force-displacement evaluation are used to control a clinching
    process, though deviations in the clinch point geometry cannot be derived with
    this method. To overcome these limitations, the clinching process can be investigated
    using in-situ computed tomography (in-situ CT). However, a clinching tool made
    of steel would cause strong artefacts and a high attenuation in the CT measurement,
    reducing the significance of this method. Additionally, when joining parts of
    the same material, the sheet-sheet interface is hardly detectable. This work aims
    at identifying, firstly, tool materials that allow artefact-reduced CT measurements
    during clinching, and, secondly, radiopaque materials that can be applied between
    the joining parts to enhance the detectability of the sheet-sheet interface. Therefore,
    both CT-suitable tool materials and radiopaque materials are selected and experimentally
    investigated. In the clinching process, two aluminium sheets with radiopaque material
    in between are clinched in a single-step (rotationally symmetric joint without
    cut section). It is shown that e.g. silicon nitride is suited as tool material
    and a tin layer is suitable to enhance the detectability of the sheet-sheet interface.</jats:p>@eng
