  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>The design
    of clinch joints is a cost- and time-intensive iterative process due to the complex
    relationships between tool and process parameters and the resulting joint properties.
    To address this, this contribution proposes a novel hybrid workflow that combines
    knowledge- and data-based approaches. Relationships are categorized based on their
    knowledge quality and the need for a quantitative prediction. Well-established,
    generalizable relationships are formalized in an ontology as design guidelines
    (no quantification required) or SWRL rules (quantification required) to model
    expert knowledge. In contrast, hard-to-formalize or not-fully-understood relationships
    are treated with regression models for continuous or classification models for
    binary criteria. These approaches are combined in a generic user interface (GUI),
    where the ontology can be accessed using predefined SPARQL queries to select and
    adapt parameters using expert knowledge. These parameters are then used as input
    for the metamodels. The developed workflow is evaluated on two exemplary joining
    tasks to illustrate, how designers can retrieve similar prior joints, adapt parameters
    using the encoded design rules and predict resulting joint properties under varying
    process conditions. In summary, the combination of ontology and metamodels facilitates
    the transition of trial and error into an efficient, documentable design process.</jats:p>"

  text: <jats:p>Abstract. The growing significance of lightweight design, reveals
    drawbacks of conventional joining processes such as welding, which are known to
    consume a considerable amount of energy. This fosters the use of mechanical joining
    processes including clinching. However, the lack of universally applicable design
    methods results in a cost- and time-intensive design process. The utilization
    of machine learning methods can overcome these drawbacks. To ensure a reliable
    clinch joint design, inherent uncertainties of the design parameter such as tool
    deviations need to be considered in the design process. Varying distributions
    of design parameters, due to changes in the manufacturing process, can lead to
    high-computational effort in recalculating the resulting clinch joint properties
    with numerical simulations. Current metamodel-based methods for consideration
    of inherent uncertainties within the design parameters do not investigate the
    transferability of metamodels to different distributions of design parameters,
    which can lead to incorrect predictions. Therefore, this contribution investigates
    the performance of several metamodels on differently distributed design parameters.
    The obtained results indicate that metamodels demonstrate the best performance
    when training and evaluation distributions are identical and that polynomial regression
    models perform best on disparate distributions, when trained on uniform distributions.</jats:p>

  text: Focusing on upcoming challenges in lightweight design, such as increasing
    emission targets or novel multimaterial connections, versatile applicable and
    environmentally friendly production technologies are crucial. In this context,
    mechanical joining technology clinching offers a fast and energy-efficient procedure
    for assembling sheet metals, being a proper alternative to established joining
    methods, such as spot welding. However, the design of clinch points is a challenge,
    which is partly supported by numerical or data-based approaches for optimal tool
    dimensions assuring proper joint characteristics. While this is usually done for
    an ideal environment, real joining processes are characterized by multiple inevitably
    varying parameters, e.g. of the material, which have a significant impact on the
    quality of clinch points. Therefore, this contribution addresses the current gap
    by analyzing the effect of parameter variations or uncertainties on the resulting
    joint characteristics and studying the impact of the nominal tool design. Thus,
    an efficient meta-model-based variation simulation procedure is proposed and used
    for analyzing the effect of different tool design configurations and variation
    scenarios. Based on the results, it was found that varying process parameters
    have a strong impact on the resulting joint characteristics, whereby the effect
    significantly depends on the nominal tool design. This reveals the potential for
    a robust tool design and implies that the nominal tool design and the tolerancing
    of parameters should be done simultaneously for a reliable virtual joining point
    design without extensive iterations and physical tests.

  text: The focus towards multi-material and lightweight assemblies, driven by legal
    requirements on reducing emissions and energy consumptions, reveals important
    drawbacks and disadvantages of established joining processes, such as welding.
    In this context, mechanical joining technologies, such as clinching, are becoming
    more and more relevant especially in the automotive industry. However, the availability
    of only few standards and almost none systematic design methods causes a still
    very time- and cost-intensive assembly development process considering mainly
    expert knowledge and a considerable amount of experimental studies. Motivated
    by this, the presented work introduces a novel approach for the methodical design
    and dimensioning of mechanically clinched assemblies. Therefore, the utilization
    of regression models, such as machine learning algorithms, combined with manufacturing
    knowledge ensures a reliable estimation of individual clinched joint characteristics.
    In addition, the implementation of an engineering workbench enables the following
    data-driven and knowledge-based generation of high-quality initial assembly designs
    already in early product development phases. In a subsequent analysis and adjustment,
    these designs are being improved while guaranteeing joining safety and loading
    conformity. The presented results indicate that the methodological approach can
    pave the way to a more systematic design process of mechanical joining assemblies,
    which can significantly shorten the required number of iteration loops and therefore
    the product development time.

  text: Challenges in the development of resource-efficient lightweight designs, such
    as emission and cost targets in production, lead to an increasing demand for environmentally
    friendly and fast joining processes. Therefore, cold-forming mechanical joining
    techniques provide an energy-efficient alternative in comparison to established
    processes, such as spot welding. However, to ensure a sufficient reliability of
    the product design, not only the selection of an appropriate manufacturing and
    joining method, but also the suitable dimensioning and validation of the entire
    joining process is a crucial step. In this context, thermal processes offer a
    large number of design principles while mechanical joining methods mainly require
    extensive experimental tests and the inclusion of expert knowledge. Although few
    contributions already investigated the data-based analysis of mechanical joints,
    a system for the requirement- and manufacturing-oriented dimensioning of joining
    components, such as different profiles and blanks, in combination with the estimation
    of joint properties is not available yet. Motivated by this lack, this contribution
    introduces an engineering workbench for the support of design engineers in the
    early development phases of the knowledge and data-based design of mechanical
    joining connections using clinching as an example. In this regard, the approach
    is demonstrated involving a similar material and sheet thickness combination with
    static loads.

  text: Given strict emission targets and legal requirements, especially in the automotive
    industry, environmentally friendly and simultaneously versatile applicable production
    technologies are gaining importance. In this regard, the use of mechanical joining
    processes, such as clinching, enable assembly sheet metals to achieve strength
    properties similar to those of established thermal joining technologies. However,
    to guarantee a high reliability of the generated joint connection, the selection
    of a best-fitting joining technology as well as the meaningful description of
    individual joint properties is essential. In the context of clinching, few contributions
    have to date investigated the metamodel-based estimation and optimization of joint
    characteristics, such as neck or interlock thickness, by applying machine learning
    and genetic algorithms. Therefore, several regression models have been trained
    on varying databases and amounts of input parameters. However, if product engineers
    can only provide limited data for a new joining task, such as incomplete information
    on applied joining tool dimensions, previously trained metamodels often reach
    their limits. This often results in a significant loss of prediction quality and
    leads to increasing uncertainties and inaccuracies within the metamodel-based
    design of a clinch joint connection. Motivated by this, the presented contribution
    investigates different machine learning algorithms regarding their ability to
    achieve a satisfying estimation accuracy on limited input data applying a statistically
    based feature selection method. Through this, it is possible to identify which
    regression models are suitable to predict clinch joint characteristics considering
    only a minimum set of required input features. Thus, in addition to the opportunity
    to decrease the training effort as well as the model complexity, the subsequent
    formulation of design equations can pave the way to a more versatile application
    and reuse of pretrained metamodels on varying tool configurations for a given
    clinch joining task.

  text: The trend towards lightweight design, driven by increasingly stringent emission
    targets, poses challenges to conventional joining processes due to the different
    mechanical properties of the joining partners used to manufacture multi-material
    systems. For this reason, new versatile joining processes are in demand for joining
    dissimilar materials. In this regard, pin joining with cold extruded pin structures
    is a relatively new, two-stage joining process for joining materials such as high-strength
    steel and aluminium as well as steel and fibre-reinforced plastic to multi-material
    systems, without the need for auxiliary elements. Due to the novelty of the process,
    there are currently only a few studies on the robustness of this joining process
    available. Thus, limited statements on the stability of the joining process considering
    uncertain process conditions, such as varying material properties or friction
    values, can be provided. Motivated by this, the presented work investigates the
    influence of different uncertain process parameters on the pin extrusion as well
    as on the joining process itself, carrying out a systematic robustness analysis.
    Therefore, the methodical approach covers the complete process chain of pin joining,
    including the load-bearing capacity of the joint by means of numerical simulation
    and data-driven methods. Thereby, a deeper understanding of the pin joining process
    is generated and the versatility of the novel joining process is increased. Additionally,
    the provision of manufacturing recommendations for the forming of pin joints leads
    to a significant decrease in the failure probability caused by ploughing or buckling
    effects.

  text: Given a steadily increasing demand on multi-material lightweight designs,
    fast and cost-efficient production technologies, such as the mechanical joining
    process clinching, are becoming more and more relevant for series production.
    Since the application of such joining techniques often base on the ability to
    reach similar or even better joint loading capacities compared to established
    joining processes (e.g., spot welding), few contributions investigated the systematic
    improvement of clinch joint characteristics. In this regard, the use of data-driven
    methods in combination with optimization algorithms showed already high potentials
    for the analysis of individual joints and the definition of optimal tool configurations.
    However, the often missing consideration of uncertainties, such as varying material
    properties, and the related calculation of their impact on clinch joint properties
    can lead to poor estimation results and thus to a decreased reliability of the
    entire joint connection. This can cause major challenges, especially for the design
    and dimensioning of safety-relevant components, such as in car bodies. Motivated
    by this, the presented contribution introduces a novel method for the robust estimation
    of clinch joint characteristics including uncertainties of varying and versatile
    process chains in mechanical joining. Therefore, the utilization of Gaussian process
    regression models is demonstrated and evaluated regarding the ability to achieve
    sufficient prediction qualities.

  text: Since the application of mechanical joining methods, such as clinching or
    riveting, offers a robust solution for the generation of advanced multi-material
    connections, the use in the field of lightweight designs (e.g. automotive industry)
    is steadily increasing. Therefore, not only the design of an individual joint
    is required but also the dimensioning of the entire joining connection is crucial.
    However, in comparison to thermal joining techniques, such as spot welding, the
    evaluation of the joints’ resistance against defined requirements (e.g. types
    of load, minimal amount of load cycles) mainly relies on the consideration of
    expert knowledge, a few design principles and a small amount of experimental data.
    Since this generally implies the involvement of several domains, such as the material
    characterization or the part design, a tremendous amount of data and knowledge
    is separately generated for a certain dimensioning process. Nevertheless, the
    lack of formalization and standardization in representing the gained knowledge
    leads to a difficult and inconsistent reuse, sharing or searching of already existing
    information. Thus, this contribution presents a specific ontology for the provision
    of cross-domain knowledge about mechanical joining processes and highlights two
    potential use cases of this ontology in the design of clinched and pin joints.</jats:p>

  text: Due to increasingly strict emission targets and regulatory requirements, especially
    for companies in the transport industry, the demand for multi-material-systems
    is continuously rising in order to lower energy consumption. In this context,
    mechanical joining processes offer an environmentally friendly and flexible alternative
    to established joining methods, especially in the field of lightweight design.
    For example, cold-formed cylindrical pin structures show high potentials in joining
    multi-material-systems without auxiliary elements. The pin structures are joined
    either by pressing them directly into the joining partner or by caulking with
    a pre-punched part. However, to evaluate the strength of the joint and to ensure
    the joining reliability for versatile processes, such as changing joining partners
    or batch variations, engineering designers currently have only limited design
    principles available compared to thermal joining processes. Consequently, the
    design of an optimal pin joint requires cost- and time-intensive experimental
    investigations and adjustments to design or process parameters. As a solution,
    data-driven methods offer procedures for structuring data and identifying dependencies
    between varying process parameters and resulting pin structure characteristics.
    Motivated by this, the paper presents an approach for the data-driven analysis
    of cold-formed pin structures and offers a deeper understanding of how versatile
    processes affect the pin characteristics. Therefore, the application of an intelligent
    design of experiment in combination with several machine learning methods enable
    the setup of a best-fitting meta-model. Resulting, the determination of a mathematical
    model provides the opportunity to accurately estimate the pin height considering
    only relevant geometrical and process parameters with a prediction quality of
    95 %.

abstract:
- lang: eng
  text: 'Due to their cost-efficiency and environmental friendliness, the demand of
    mechanical joining processes is constantly rising. However, the dimensioning and
    design of joints and suitable processes are mainly based on expert knowledge and
    few experimental data. Therefore, the performance of numerical and experimental
    studies enables the generation of optimized joining geometries. However, the manual
    evaluation of the results of such studies is often highly time-consuming. As a
    novel solution, image segmentation and machine learning algorithm provide methods
    to automate the analysis process. Motivated by this, the paper presents an approach
    for the automated analysis of geometrical characteristics using clinching as an
    example. '
