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…

Efficient equilibrium-based stress recovery for isogeometric laminated curved structures

Alessia Patton, Pablo Antolin, Josef Kiendl +1

This work focuses on an efficient stress recovery procedure for laminated composite curved structures, which relies on Isogeometric Analysis (IGA) and equilibrium. Using a single e…

Accurate equilibrium-based interlaminar stress recovery for isogeometric laminated composite Kirchhoff plates

Alessia Patton, Pablo Antolin, John-Eric Dufour +2

In this paper, we use isogeometric Kirchhoff plates to approximate composite laminates adopting the classical laminate plate theory. Both isogeometric Galerkin and collocation form…

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 simple and effective method based on strain projections to alleviate locking in isogeometric solid shells

Pablo Antolin, Josef Kiendl, Marco Pingaro +1

In this work, we focus on the family of shell formulations referred to as "solid shells", where the simulation of shell-type structures is performed by means of a mesh of 3D solid…
