BDDC Deluxe for Isogeometric Analysis [PDF]
, 2016 The main goal of this paper is to design, analyze, and test a BDDC (Balancing Domain Decomposition by Constraints, see [12, 23]) preconditioner for Isogeometric Analysis (IGA), based on a novel type of interface averaging, which we will denote by deluxe scaling, with either full or reduced set of primal constraints.

Computer Graphics Forum, EarlyView.Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

An isogeometric Reissner–Mindlin shell element based on mixed grid
Advances in Mechanical Engineering, 2018 We propose in this article a new isogeometric Reissner–Mindlin degenerated shell element for linear analysis. It is based on the mixed use of non-uniform rational basis spline and Lagrange basis functions in the same domain.

Isogeometric analysis of two-dimensional piezoelectric structures
Vietnam Journal of Mechanics, 2013 The isogeometric analysis (IGA) that integrates Computer Aided Design(CAD) and Computer Aided Engineering (CAE) is found so far the effectively numerical tool for the analysis of a variety of practical problems.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.ABSTRACT Numerous mesh‐distortion‐insensitive Petrov‐Galerkin finite element formulations have been developed for the simulation of elastostatic problems. This contribution presents initial results on how these formulations can be extended to linear elastodynamics. In this context, three different approaches are examined, building upon an established 8‐

Isogeometric Analysis of FGM Plates
Materials Today: Proceedings, 2018 Abstract This work presents an isogeometric formulation for the geometrically nonlinear analysis of functionally graded material (FGM) plates. FGM plates are made of a mixture of two components (ceramic and metal) whose volume fractions vary smoothly along the thickness.

Isogeometric analysis: vibration analysis, Fourier and wavelet spectra [PDF]
Journal of Theoretical and Applied Vibration and Acoustics, 2017 This paper presents the Fourier and wavelet characterization of vibration problem. To determine the natural frequencies, modal damping and mass participation factors of bars, a rod element is established by means ofisogeometric formulation.

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.ABSTRACTLattice systems are indispensable for modeling and analyzing physical phenomena in materials with discrete or heterogeneous micro‐ or meso‐structures. However, the computational requirements for practical engineering applications of lattice systems remain high.
