Two-level Method Part-scale Thermal Analysis of Laser Powder Bed Fusion Additive Manufacturing
Massimo Carraturo, Alex Viguerie, Alessandro Reali +1
Numerical simulations of a complete laser powder bed fusion (LPBF) additive manufacturing (AM) process are extremely challenging or even impossible to achieve without a radical mod…
A spatiotemporal two-level method for high-fidelity thermal analysis of laserpowder bed fusion
Alex Viguerie, Massimo Carraturo, Alessandro Reali +1
Numerical simulation of the laser powder bed fusion (LPBF) procedure for additive manufacturing (AM) is difficult due to the presence of multiple scales in both time and space, ran…
Coupled and Uncoupled Dynamic Mode Decomposition in Multi-Compartmental Systems with Applications to Epidemiological and Additive Manufacturing Problems
Alex Viguerie, Gabriel F. Barros, Malú Grave +2
Dynamic Mode Decomposition (DMD) is an unsupervised machine learning method that has attracted considerable attention in recent years owing to its equation-free structure, ability…
Topology-preserving Scan-based Immersed Isogeometric Analysis
S. C. Divi, C. V. Verhoosel, F. Auricchio +2
To exploit the advantageous properties of isogeometric analysis (IGA) in a scan-based setting, it is important to extract a smooth geometric domain from the scan data (e.g., voxel…
Dynamic Mode Decomposition in Adaptive Mesh Refinement and Coarsening Simulations
Gabriel F. Barros, Malú Grave, Alex Viguerie +2
Dynamic Mode Decomposition (DMD) is a powerful data-driven method used to extract spatio-temporal coherent structures that dictate a given dynamical system. The method consists of…
Mixed variational formulations for structural topology optimization based on the phase-field approach
Michele Marino, Ferdinando Auricchio, Alessandro Reali +2
We propose a variational principle combining a phase-field functional for structural topology optimization with a mixed (three-field) Hu-Washizu functional, then including directly…
