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…
Structure-Preserving Invariant Interpolation Schemes for Invertible Second-Order Tensors
Abhiroop Satheesh, Christoph P. Schmidt, Wolfgang A. Wall +1
Tensor interpolation is an essential step for tensor data analysis in various fields of application and scientific disciplines. In the present work, novel interpolation schemes for…
Quantitative analysis of thin metal powder layers via transmission X-ray imaging and discrete element simulation: Blade-based spreading approaches
Ryan W. Penny, Daniel Oropeza, Patrick M. Praegla +4
Spreading uniform and dense layers is of paramount importance to creating high-quality components using powder bed additive manufacturing (AM). Blade-like tools are often employed…
