Influence of Extruded Filament Shape on Buildability in 3D Concrete Printing: A Geometry-Informed Deep Learning-FEM Approach
Giacomo Rizzieri, Saif-Ur-Rehman, Jörg F. Unger +1
The geometric morphology of deposited filaments can significantly influence the structural performance and stability of 3D concrete-printed (3DCP) structures. However, most finite…
Buildability Assessment of 3D-Printed Concrete Structures Using Smoothed Mohr-Coulomb Plasticity with Isotropic Hardening
Saif-Ur-Rehman, Annika Robens-Radermacher, R. J. M. Wolfs +1
Extrusion-based 3D concrete printing builds structural elements layer upon layer without formwork, so freshly deposited material must carry the growing weight of the structure whil…
Quantifying water-driven geometric uncertainties in powder bed concrete printing using high-resolution 3D modeling
Christoph Wolf, Petr Hlaváček, Annika Robens-Radermacher +2
Dimensional accuracy in powder bed 3D printing of concrete is strongly influenced by binder distribution, and the resulting geometric deviations can be direction-dependent. This st…
Multiscale modeling of linear elastic heterogeneous structures via localized model order reduction
Philipp Diercks, Karen Veroy, Annika Robens-Radermacher +1
In this paper, a methodology for fine scale modeling of large scale structures is proposed, which combines the variational multiscale method, domain decomposition and model order r…
