Accelerating structural optimization via EIFEM: a ROM-based preconditioner
Raul Rubio, Alex Ferrer, Joaquin Alberto Hernandez +1
Topology optimization (TopOpt) is a standard tool for structural conceptual design, providing optimal structures with great design freedom. However, it has a high computational cos…
Deflation-based preconditioning for immersed finite element methods and immersogeometric analysis
Yannis Voet, Matthias Möller, Pablo Antolin +1
Trimming is a ubiquitous operation in computer-aided-design whereby parts of a geometry are merged, intersected, or simply discarded. While it grants virtually unlimited flexibilit…
Immersed boundary-conformal isogeometric methods for magnetostatics
Yusuf T. Elbadry, Giuliano Guarino, Pablo Antolín +1
Isogeometric analysis was proposed to bridge the gap between computer-aided design and numerical discretization. However, standard multi-patch isogeometric analysis mandates confor…
A ROM-based BDDC solver for unfitted p-FEM level-set-based two-dimensional lattice structures
Gonzalo Bonilla Moreno, Giuliano Guarino, Pablo Antolin
We present a domain decomposition method for the fast simulation of large two-dimensional lattice structures described by level set functions. The method does not rely on homogeniz…
Efficient Fine-Scale Simulation of Nonlinear Hyperelastic Lattice Structures
Clément Guillet, Thibaut Hirschler, Pierre Jolivet +2
With the growing maturity of additive manufacturing, the fabrication of architected or lattice-based metamaterials has become a reality for industrial applications. These materials…
A General and Robust 3D Finite Element Dynamics Framework for Railway Vehicle-Bridge Interaction with Nonlinear Wheel-Rail Contact Modeling
Pablo Antolin, Khanh Nguyen, José M. Goicolea
A key challenge in 3D finite element models of coupled railway vehicle-bridge dynamics is the rigorous definition of kinematic constraints and the development of an efficient, robu…
On design, analysis, and hybrid manufacturing of microstructured blade-like geometries
Pablo Antolin, Michael Barton, Georges-Pierre Bonneau +17
With the evolution of new manufacturing technologies such as multi-material 3D printing, one can think of new type of objects that consist of considerably less, yet heterogeneous,…
Variable offsets and processing of implicit forms toward the adaptive synthesis and analysis of heterogeneous conforming microstructure
Q. Y. Hong, P. Antolin, G. Elber +1
The synthesis of porous, lattice, or microstructure geometries has captured the attention of many researchers in recent years. Implicit forms, such as triply periodic minimal surfa…
