Investigation of the Peeling and Pull-off Behavior of Adhesive Elastic Fibers via a Novel Computational Beam Interaction Model
Maximilian J. Grill, Christoph Meier, Wolfgang A. Wall
This article studies the fundamental problem of separating two adhesive elastic fibers based on numerical simulation employing a recently developed finite element model for molecul…
A Computational Model for Molecular Interactions Between Curved Slender Fibers Undergoing Large 3D Deformations With a Focus on Electrostatic, van der Waals and Repulsive Steric Forces
Maximilian J. Grill, Wolfgang A. Wall, Christoph Meier
This contribution proposes the first 3D beam-to-beam interaction model for molecular interactions between curved slender fibers undergoing large deformations. While the general mod…
Extended Comment on the Article "Consistent Development of a Beam-To-Beam Contact Algorithm via the Curve to Solid Beam Contact - Analysis for the Non-Frictional Case"
Christoph Meier, Alexander Popp, Wolfgang A. Wall
In the authors' previous works, novel finite element formulations for the contact interaction of slender beams have been proposed. In their recent article "Consistent Development o…
Critical Influences of Particle Size and Adhesion on the Powder Layer Uniformity in Metal Additive Manufacturing
Christoph Meier, Reimbar Weissbach, Johannes Weinberg +2
The quality of powder layers, specifically their packing density and surface uniformity, is a critical factor influencing the quality of components produced by powder bed metal add…
Modeling and Characterization of Cohesion in Fine Metal Powders with a Focus on Additive Manufacturing Process Simulations
Christoph Meier, Reimar Weissbach, Johannes Weinberg +2
The cohesive interactions between fine metal powder particles crucially influence their flow behavior, which is in turn important to many powder-based manufacturing processes inclu…
