The assessment of mechanically joined connections, such as clinched connections, is usually conducted destructively. Applicable non-destructive testing methods like computed tomography are time-consuming and costly, or, like electrical resistance measurement, provide only a limited amount of information. A fast, non-destructive evaluation of the joints condition shall be made possible by using transient dynamic analysis (TDA). It is based on the introduction of sound waves and the evaluation of the response behavior after passing through the structure. This study focuses the application of TDA to clinched shear connections to evaluate the performance of the tactile measuring setup. Twenty-one series were investigated, covering variations in joining task, manufacturing and defect. The evaluation was carried out using machine learning to determine for which series characteristic signals may be detected. It was shown that a classification of the investigated specimens is possible, whereby the classification accuracy depends on the examined variation. Furthermore, the accuracy was evaluated as a function of frequency and results were concluded to identify the limits of the used measuring setup.</jats:p> Materials Research Forum LLC2025Paderborn eng JoiningMachine LearningTransient Dynamic Analysis 2474-395X10.21741/9781644903551-36 52293-300 Reschke, Gregor, and Alexander Brosius. “Transient Dynamic Analysis: Performance Evaluation of Tactile Measurement.” <i>Materials Research Proceedings</i>, vol. 52, Materials Research Forum LLC, 2025, pp. 293–300, doi:<a href="https://doi.org/10.21741/9781644903551-36">10.21741/9781644903551-36</a>.
