  text: <jats:p>The mechanical joining of continuous fiber-reinforced thermoplastics
    (cFRTP) and metal sheets represents a promising approach for manufacturing hybrid
    lightweight structures. To reduce the time and cost associated with extensive
    experimental investigations, numerical modeling strategies are increasingly applied.
    In this numerical study, a further step in the modelling strategy for the direct
    pin-pressing (DPP) process of cFRTP and metal sheets is presented. The study focuses
    on modeling and simulating the occurring deformation mechanisms of decomposition,
    compaction, and separation of individual rovings on the mesoscale to analyze the
    resulting material structure. For this purpose, two simplified models were derived.
    The textile architecture is represented based on micrographs of cross-sections
    and discretized using the finite element method. The deformation of individual
    rovings during joining leads to a deformation of their initial elliptical cross
    section. To capture this level of resolution, both a cohesive zone and a pure
    contact approach are applied within the rovings. The highly viscous thermoplastic
    melt is modeled as a fluid employing the Arbitrary Lagrange–Eulerian (ALE) method.
    Matrix and roving meshes are coupled to account for fluid–structure interaction
    (FSI) during process. The study shows that coupling of matrix and rovings is necessary
    to obtain more accurate predictions of the deformation behaviour. Furthermore,
    the cohesive zone approach is better suited to simulate the emerging deformation
    mechanisms.</jats:p>
