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…
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…
Automatic differentiation for solid mechanics
Andrea Vigliotti, Ferdinando Auricchio
Automatic differentiation (AD) is an ensemble of techniques that allow to evaluate accurate numerical derivatives of a mathematical function expressed in a computer programming lan…
Error-estimate-based Adaptive Integration For Immersed Isogeometric Analysis
Sai C Divi, Clemens V Verhoosel, Ferdinando Auricchio +2
The Finite Cell Method (FCM) together with Isogeometric analysis (IGA) has been applied successfully in various problems in solid mechanics, in image-based analysis, fluid-structur…
A Fat boundary-type method for localized nonhomogeneous material problems
Alex Viguerie, Silvia Bertoluzza, Ferdinando Auricchio
Problems with localized nonhomogeneous material properties arise frequently in many applications and are a well-known source of difficulty in numerical simulations. In certain appl…
