Journal ArticleDOI
Unerring Planning of Clinching Processes through the Use of Mathematical Methods
TL;DR: In this paper, the authors discuss the potentials and limits concerning FEM based sensitivity analysis and optimization for the joining by forming technology, by determining the sensitivity of the design for relevant connection parameters, the most important values for the optimization of the forming die are derived.
Journal ArticleDOI
Concept for Further Development of Self-pierce Riveting by Using Cyber Physical Systems☆
TL;DR: In this article, a numerical analysis of the most influential tool parameters as well as the influence of varying boundary conditions on the joining result for self-pierce riveting is presented, and a new concept for improving quality and flexibility of the process by using an advanced die system in combination with cyber physical systems is introduced.
Journal ArticleDOI
Gathering of Process Data through Numerical Simulation for the Application of Machine Learning Prognosis Algorithms
TL;DR: A method is shown by which application it is possible, that only on the basis the general mechanical properties and the use of data-based prognosis models of supervised machine learning to predict directly a result regarding suitable process parameters as well as expected forming result properties are shown.
Journal ArticleDOI
Adhesive Distribution and Global Deformation between Hybrid Joints
TL;DR: In this paper, the authors focus on the formation of adhesive bags during the riveting process, before the adhesive curing takes place, and use high-speed optical measurement technology like Point Tracking and surface scanning to track the resulting deformations experimentally.
Journal ArticleDOI
Development of a New Self-flaring Rivet Geometry Using Finite Element Method and Design of Experiments
TL;DR: The challenges and solution approaches associated with the modelling of material damage and separation in the three-dimensional calculation models of the riveting process are presented and the consideration of macromechanical and geometrical criteria for element deletion is important in order to obtain robust models with useful results.
