text: 'Thermally supported clinching (Hotclinch) is a novel promising process to
join dissimilar materials. Here, metal and fibre-reinforced thermoplastics (FRTP)
are used within this single step joining process and without the usage of auxiliary
parts like screws or rivets. For this purpose, heat is applied to improve the
formability of the reinforced thermoplastic. This enables joining of the materials
using conventional clinching-tools. Focus of this work is the modelling on mesoscopic
scale for the numerical simulation of this process. The FTRP-model takes the material
behaviour both of matrix and the fabric reinforced organo-sheet under process
temperatures into account. For describing the experimentally observed phenomena
such as large deformations, fibre failure and the interactions between matrix
and fibres as well as between fibres themselves, the usage of conventional, purely
Lagrangian based FEM methods is limited. Therefore, the combination of contact-models
with advanced modelling approaches like Arbitrary-Lagrangian-Eulerian (ALE), Coupled-Eulerian-Lagrangian
(CEL) and Smooth-ParticleHydrodynamics (SPH) for the numerical simulation of the
clinching process are employed. The different approaches are compared with regard
to simulation feasibility, robustness and results accuracy. It is shown, that
the CEL approach represents the most promising approach to describe the clinching
process. '

text: AbstractRecent developments in automotive
and aircraft industry towards a multi-material design pose challenges for modern
joining technologies due to different mechanical properties and material compositions
of various materials such as composites and metals. Therefore, mechanical joining
technologies like clinching are in the focus of current research activities. For
multi-material joints of metals and thermoplastic composites thermally assisted
clinching processes with advanced tool concepts are well developed. The material-specific
properties of fibre-reinforced thermoplastics have a significant influence on
the joining process and the resulting material structure in the joining zone.
For this reason, it is important to investigate these influences in detail and
to understand the phenomena occurring during the joining process. Additionally,
this provides the basis for a validation of a numerical simulation of such joining
processes. In this paper, the material structure in a joint resulting from a thermally
assisted clinching process is investigated. The joining partners are an aluminium
sheet and a thermoplastic composite (organo sheet). Using computed tomography
enables a three-dimensional investigation that allows a detailed analysis of the
phenomena in different joining stages and in the material structure of the finished
joint. Consequently, this study provides a more detailed understanding of the
material behavior of thermoplastic composites during thermally assisted clinching.
