--- _id: '59873' abstract: - lang: eng text: This paper focuses on the failure behavior of clinched specimens with various stiffnesses under shear tensile loading. The primary objective is to assess the influence of the specimen stiffness with an arrangement of clinched joints. The specimen stiffness depends on several variables. In addition to the material selection, the specific choice of geometry and the design of the clinched joints must also be taken into account. A number of experiments was conducted to investigate the failure behavior of specimens with an arrangement of three clinched joints under shear tensile loading. These configurations were subjected to shear tensile tests, with force displacement curves recorded for each specimen to provide a detailed characterization of their structural response. The stiffness is modified by altering the specimen width, which has marginal impact on the maximum force. The experimental findings indicate that reducing the specimen stiffness results in a shift in the type of stress, with the failure behavior becoming increasingly influenced by bending stress. These results offer important insights for the design of clinched joint assemblies, indicating that it is feasible to achieve the desired properties by changing the specimen stiffness. article_number: '01080' author: - first_name: Eugen full_name: Wolf, Eugen last_name: Wolf - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Wolf E, Brosius A.

At the same time, various industries are increasingly trending towards multi-material systems consisting of parts with varying geometric and mechanical properties. Due to the varying properties, rigid mechanical joining processes require sampling procedures and periodic changes of tool components or auxiliary joining parts. Consequently, research is focusing on versatile mechanical joining processes that allow increased control by modifying the process parameters. Two processes based on self-piercing riveting can achieve a significant increase in process influence possibilities through a multi-linear actuator as versatile self-piercing riveting (V-SPR) and a tumbling superimposed actuator as tumbling self-piercing riveting (T-SPR). Initial research into V-SPR has shown that this process can be used to achieve a higher variation in overall package thickness by adapting the rivet geometry and using multiple linear actuators. The T-SPR process also enables increased material flow control by means of targeted compression of the rivet using the tumbling actuator, thereby extending the range of joints that can be manufactured. Based on these two processes, a combination of the two mechanisms of action is to be developed. article_number: '01069' author: - first_name: Pia Katharina full_name: Holtkamp, Pia Katharina id: '44935' last_name: Holtkamp - first_name: Simon full_name: Wituschek, Simon id: '83423' last_name: Wituschek - first_name: Michael full_name: Lechner, Michael last_name: Lechner - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 citation: ama: Holtkamp PK, Wituschek S, Lechner M, Meschut G.

As part of the development of a method for ensuring the versatility of clinching, an additional rotational movement of the punch was introduced as a control variable to influence friction in the mechanical joining process. The effect of rotational superimposition on the force-displacement curve of the clinching processes was investigated using four test variants with different kinematics. The primary objective was to evaluate the binding mechanisms that maintain the integrity of the clinched joint. To evaluate the force closure of the resulting joint, two testing methods were employed throughout the course of the research, non-destructive resistance measurement using four-wire sensing method and destructive torsion testing. A crucial factor influencing the efficacy of the process is surface cleanliness, as contaminants between joining partners can impede the effectiveness of the clinched joint. Therefore, all specimens were meticulously cleaned prior to experimentation. This method exhibits promising potential in creating clinched joints that align with the demands of flexible manufacturing environments. article_number: '01086' author: - first_name: Stephan full_name: Lüder, Stephan last_name: Lüder - first_name: Eugen full_name: Wolf, Eugen last_name: Wolf - first_name: Hans Christian full_name: Schmale, Hans Christian last_name: Schmale - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Lüder S, Wolf E, Schmale HC, Brosius A.

The focus is on understanding how changes in the alignment of individual joints affect the distribution of load, neighboring joints, and the overall performance of the component. Lap shear specimens with multiple joints arranged in a line are analyzed to explore these effects. Simplified models are used to model the joints in finite element simulations, allowing for efficient yet accurate analysis of the load distribution and structural response under varying joint orientations. Variations in joint orientation result in measurable changes in the distribution of forces on adjacent joints, influencing their behavior and that of the overall assembly. Experimental validation confirms the numerical results, providing deeper insights into the interaction between individual joints and their surroundings. This work contributes to the development of systematic approaches for optimizing the design of components with non-rotationally symmetric joints. The study highlights the importance of considering directional properties of joints in designing structural components. article_number: '01035' author: - first_name: Deekshith Reddy full_name: Devulapally, Deekshith Reddy id: '76837' last_name: Devulapally - first_name: Christian full_name: Steinfelder, Christian last_name: Steinfelder - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Devulapally DR, Steinfelder C, Tröster T, Brosius A.
