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…
A Versatile SPH Modeling Framework for Coupled Microfluid-Powder Dynamics in Additive Manufacturing: Binder Jetting, Material Jetting, Directed Energy Deposition and Powder Bed Fusion
Sebastian L. Fuchs, Patrick M. Praegla, Christian J. Cyron +2
Many additive manufacturing (AM) technologies rely on powder feedstock, which is fused to form the final part either by melting or by chemical binding with subsequent sintering. In…
A Mortar Finite Element Formulation for Large Deformation Lubricated Contact Problems with Smooth Transition Between Mixed, Elasto-Hydrodynamic and Full Hydrodynamic Lubrication
Mostafa Faraji, Alexander Seitz, Christoph Meier +1
This work proposes a novel model and numerical formulation for lubricated contact problems describing the mutual interaction between two deformable 3D solid bodies and an interpose…
