Finite Element Formulations for Beam-to-Solid Interaction -- From Embedded Fibers Towards Contact
Alexander Popp, Ivo Steinbrecher
Contact and related phenomena, such as friction, wear or elastohydrodynamic lubrication, remain as one of the most challenging problem classes in nonlinear solid and structural mec…
Consistent coupling of positions and rotations for embedding 1D Cosserat beams into 3D solid volumes
Ivo Steinbrecher, Alexander Popp, Christoph Meier
This article proposes a mortar type finite element formulation for consistently embedding curved, slender beams, i.e. 1D Cosserat continua, into 3D solid volumes. A consistent 1D-3…
A simple yet consistent constitutive law and mortar-based layer coupling schemes for thermomechanical macroscale simulations of metal additive manufacturing processes
Sebastian D. Proell, Wolfgang A. Wall, Christoph Meier
This article proposes a coupled thermomechanical finite element model tailored to the macroscale simulation of metal additive manufacturing processes such as selective laser meltin…
Generalized Section-Section Interaction Potentials in the Geometrically Exact Beam Theory: Modeling of Intermolecular Forces, Asymptotic Limit as Strain-Energy Function, and Formulation of Rotational Constraints
Christoph Meier, Maximilian J. Grill, Wolfgang A. Wall
The present contribution proposes a universal framework to formulate generalized section-section interaction potentials (SSIP) within the geometrically exact beam theory. By exploi…
Spatial Mapping of Powder Layer Density for Metal Additive Manufacturing via X-ray Microscopy
Ryan W. Penny, Patrick M. Praegla, Marvin Ochsenius +4
Uniform powder spreading is a requisite for creating consistent, high-quality components via powder bed additive manufacturing (AM), wherein layer density and uniformity are comple…
An SPH framework for fluid-solid and contact interaction problems including thermo-mechanical coupling and reversible phase transitions
Sebastian L. Fuchs, Christoph Meier, Wolfgang A. Wall +1
The present work proposes an approach for fluid-solid and contact interaction problems including thermo-mechanical coupling and reversible phase transitions. The solid field is ass…
