A novel mesh regularization approach based on finite element distortion potentials: Application to material expansion processes with extreme volume change
Abhiroop Satheesh, Christoph P. Schmidt, Wolfgang A. Wall +1
The accuracy of finite element solutions is closely tied to the mesh quality. In particular, geometrically nonlinear problems involving large and strongly localized deformations of…
Exploration of improved, roller-based spreading strategies for cohesive powders in additive manufacturing via coupled DEM-FEM simulations
Reimar Weissbach, Patrick M. Praegla, Wolfgang A. Wall +2
Spreading of fine (D50 <=20um) powders into thin layers typically requires a mechanism such as a roller to overcome the cohesive forces between particles. Roller-based spreading re…
Towards Additively Manufactured Metamaterials with Powder Inclusions for Controllable Dissipation: The Critical Influence of Packing Density
Patrick M. Praegla, Thomas Mair, Andreas Wimmer +5
Particle dampers represent a simple yet effective means to reduce unwanted oscillations when attached to structural components. Powder bed fusion additive manufacturing of metals a…
A highly efficient computational framework for fast scan-resolved simulations of metal additive manufacturing processes on the scale of real parts
Sebastian D. Proell, Peter Munch, Martin Kronbichler +2
This article proposes a novel high-performance computing approach for the prediction of the temperature field in powder bed fusion (PBF) additive manufacturing processes. In contra…
