Weighted quadrature for hierarchical B-splines
C. Giannelli, T. Kanduc, M. Martinelli, G. Sangalli and M. Tani
We present weighted quadrature for hierarchical B-splines to address the fast formation of system matrices arising from adaptive isogeometric Galerkin methods with suitably graded hierarchical meshes....

Parametric shape optimization for combined additive-subtractive manufacturing
L. Tamellini, M.Chiumenti, C. Altenhofen, M. Attene, O. Barrowclough, M. Livesu, F. Marini, M. Martinelli, and V. Skytt V.
In industrial practice, additive manufacturing (AM) processes are often followed by post-processing operations such as heat treatment, subtractive machining, milling, etc., to achieve the desired surf...

Isogeometric analysis on V-reps: First results
P. Antolin, A. Buffa, and M. 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 construction of isogeometri...

Efficient matrix computation for tensor-product isogeometric analysis: The use of sum factorization
P. Antolin, A. Buffa, F. Calabro', M. Martinelli, and G. Sangalli
In this paper we discuss the use of the sum-factorization for the calculation of the integrals arising in Galerkin isogeometric analysis. While introducing very little change in an isogeometric code b...

An isogeometric method for the Reissner-Mindlin plate bending problem
L. Beirao da Veiga, A. Buffa, C. Lovadina, M. Martinelli, and G. Sangalli
We present a new isogeometric method for the discretization of the Reissner-Mindlin plate bending problem. The proposed scheme follows a recent theoretical framework that makes possible the constructi...
