Algebraic multigrid methods for saddle point systems arising from mortar contact formulations
Tobias A. Wiesner, Matthias Mayr, Alexander Popp +2
In this paper, a fully aggregation-based algebraic multigrid strategy is developed for nonlinear contact problems of saddle point type using a mortar finite element approach. While…
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…
On phase change and latent heat models in metal additive manufacturing process simulation
Sebastian D. Proell, Wolfgang A. Wall, Christoph Meier
This work proposes an extension of phase change and latent heat models for the simulation of metal powder bed fusion additive manufacturing processes on the macroscale and compares…
A consistent and comprehensive computational approach for general Fluid-Structure-Contact Interaction problems
Christoph Ager, Alexander Seitz, Wolfgang A. Wall
We present a consistent approach that allows to solve challenging general nonlinear fluid-structure-contact interaction (FSCI) problems. The underlying continuous formulation inclu…
