Abstract In this paper, the development of algorithm-based process models for the mechanical joining process self-pierce riveting with semi-tubular rivet (SPR-ST) is described. Therefore, an extensive experimental and numerical database regarding the SPR-ST process and strength of steel and aluminum joints with tensile strengths of the sheets between 200 and 1000 MPa was generated for the building of the models. This process data could then be used for the training and evaluation of different prediction algorithms. Furthermore, the simulation data is applied to predict the entire contour (mesh) of non-simulated joints. This includes the visualization of output values such as strains, stresses and damage for each element and node of the mesh. That approach enables to obtain more information about the joint than just discrete values such as interlock or strength. read more

Data-Based and Analytical Models for Strength Prediction of Mechanical Joints
TL;DR: In this article , the numerical data-acquisition and the development of algorithm-based and analytical models for strength prediction for SPR-ST and clinching for production is described, which enables an immediate prediction of the quasi-static joint strength based on the input parameters such as properties of the parts to be joined and process parameters.

Self-pierce riveting of multiple steel and aluminium alloy sheets
TL;DR: In this paper, multiple steel and aluminium alloy sheets were joined by self-pierce riveting, and the joinability was improved by setting a softer sheet uppermost due to smooth piercing.
