text: ' Clinching is a mechanical joining technology, in which a mainly
form-fit joint is created by means of local cold forming. To characterize the
load-bearing behavior of such joints, they are typically analyzed destructively,
for example by tensile-shear tests in combination with metallographic sections.
However, both the initiation and progress of failure can only be described to
a limited extent by this method. Furthermore, these tests allow only limited conclusions
about clinch points under in-service loading. More purposefully, clinch points
can be analyzed nondestructively by combining in-situ computed tomography (CT)
and transient dynamic analysis (TDA). The TDA continuously measures the dynamic
behavior of the specimen and indicates failure events like crack initiation, which
then can be evaluated thoroughly by stopping the test and performing a CT scan.
To qualify the TDA for this task, it is necessary to link the observed damage
behavior with specific dynamic characteristics. In this work, the complementation
of in-situ CT and TDA is investigated by testing a clinched single-lap tensile-shear
specimen made of aluminum. The testing procedure is stepwise: at certain displacement
levels, the specimen is investigated by in-situ CT and TDA. While the in-situ
CT provides the location, extent, and development of the failure phenomena, the
TDA uses this information to evaluate the dynamic signal and detect relevant frequency
ranges, which indicate damage events. The results demonstrate, that failure initiation
and progression can be analyzed efficiently by combining both measuring systems.
The TDA reliably detects relevant signal changes in the monitored frequency band.
By means of in-situ computed tomography, the corresponding failure phenomena can
be described in detail, enhancing the understanding of the load-bearing and deformation
behavior of clinch points. The concatenation of characteristic signal changes
and observed failure phenomena can henceforth be transferred to analyze complex
structures during operation nondestructively by TDA. '
