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,…
Stabilization techniques for immersogeometric analysis of plate and shell problems in explicit dynamics
Giuliano Guarino, Yannis Voet, Pablo Antolin +1
Finite element plate and shell formulations are ubiquitous in structural analysis for modeling all kinds of slender structures, both for static and dynamic analyses. The latter are…
Mass lumping and stabilization for immersogeometric analysis
Yannis Voet, Espen Sande, Annalisa Buffa
Trimmed (multi-patch) geometries are the state-of-the-art technology in computer-aided design for industrial applications such as automobile crashworthiness. In this context, fast…
A theoretical analysis of mass scaling techniques
Yannis Voet, Espen Sande, Annalisa Buffa
Mass scaling is widely used in finite element models of structural dynamics for increasing the critical time step of explicit time integration methods. While the field has been flo…
The Immersed Boundary Conformal Method for Kirchhoff-Love and Reissner-Mindlin shells
Giuliano Guarino, Alberto Milazzo, Annalisa Buffa +1
This work utilizes the Immersed Boundary Conformal Method (IBCM) to analyze Kirchhoff-Love and Reissner-Mindlin shell structures within an immersed domain framework. Immersed bound…
An Interior Penalty coupling strategy for Isogeometric non-conformal Kirchhoff-Love shell patches
Giuliano Guarino, Pablo Antolin, Alberto Milazzo +1
This work focuses on the coupling of trimmed shell patches using Isogeometric Analysis, based on higher continuity splines that seamlessly meet the requirement of Kirchhoff-L…
Mass lumping and outlier removal strategies for complex geometries in isogeometric analysis
Yannis Voet, Espen Sande, Annalisa Buffa
Mass lumping techniques are commonly employed in explicit time integration schemes for problems in structural dynamics and both avoid solving costly linear systems with the consist…
An equilibrated flux a posteriori error estimator for defeaturing problems
Annalisa Buffa, Ondine Chanon, Denise Grappein +2
An a posteriori error estimator based on an equilibrated flux reconstruction is proposed for defeaturing problems in the context of finite element discretizations. Defeaturing cons…
Energy conservative isogeometric techniques for the wave equation
Andrea Bressan, Annalisa Buffa, Alen Kushova +1
We analyze the wave equation in mixed form, with periodic and/or Dirichlet homogeneous boundary conditions, and nonconstant coefficients that depend on the spatial variable. For th…
Fast and Multiscale Formation of Isogeometric matrices of Microstructured Geometric Models
Thibaut Hirschler, Pablo Antolin, Annalisa Buffa
The matrix formation associated to high-order discretizations is known to be numerically demanding. Based on the existing procedure of interpolation and lookup, we design a multisc…
Immersed Boundary-Conformal Isogeometric Method for Linear Elliptic Problems
Xiaodong Wei, Benjamin Marussig, Pablo Antolin +1
We present a novel isogeometric method, namely the Immersed Boundary-Conformal Method (IBCM), that features a layer of discretization conformal to the boundary while employing a si…
A hierarchical approach to the a posteriori error estimation of isogeometric Kirchhoff plates and Kirchhoff-Love shells
Pablo Antolin, Annalisa Buffa, Luca Coradello
This work focuses on the development of a posteriori error estimates for fourth-order, elliptic, partial differential equations. In particular, we propose a novel algorithm to stee…
