Overlapping Multi-Patch Isogeometric Method with Minimal Stabilization
Pablo Antolin, Annalisa Buffa, Riccardo Puppi +1
We present a novel method for isogeometric analysis (IGA) to directly work on geometries constructed by Boolean operations including difference (i.e., trimming), union and intersec…
Adaptive isogeometric analysis on two-dimensional trimmed domains based on a hierarchical approach
Luca Coradello, Pablo Antolin, Rafael Vázquez +1
The focus of this work is on the development of an error-driven isogeometric framework, capable of automatically performing an adaptive simulation in the context of second- and fou…
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…
Optimizing micro-tiles in micro-structures as a design paradigm
Pablo Antolin, Annalisa Buffa, Elaine Cohen +5
In recent years, new methods have been developed to synthesize complex porous and micro-structured geometry in a variety of ways. In this work, we take these approaches one step fu…
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…
Fast assembly of Galerkin matrices for 3D solid laminated composites using finite element and isogeometric discretizations
Pablo Antolin
This work presents a novel methodology for speeding up the assembly of stiffness matrices for laminate composite 3D structures in the context of isogeometric and finite element dis…
Volumetric Untrimming: Precise decomposition of trimmed trivariates into tensor products
Fady Massarwi, Pablo Antolin, Gershon Elber
3D objects, modeled using Computer Aided Geometric Design tools, are traditionally represented using a boundary representation (B-rep), and typically use spline functions to parame…
Isogeometric Analysis on V-reps: first results
Pablo Antolin, Annalisa Buffa, Massimiliano Martinelli
Inspired by the introduction of Volumetric Modeling via volumetric representations (V-reps) by Massarwi and Elber in 2016, in this paper we present a novel approach for the constru…
Fast and accurate elastic analysis of laminated composite plates via isogeometric collocation and an equilibrium-based stress recovery approach
Alessia Patton, John-Eric Dufour, Pablo Antolin +1
A novel approach which combines isogeometric collocation and an equilibrium-based stress recovery technique is applied to analyze laminated composite plates. Isogeometric collocati…
