APPROXIMATION BY LOCAL PARABOLIC SPLINES CONSTRUCTED ON THE BASIS OF INTERPOLATION IN THE MEAN

open access: yesUral Mathematical Journal, 2017
The paper deals with approximative and form-retaining properties of the local parabolic splines of the form \(S(x)=\sum\limits_j y_j B_2 (x-jh),\) \( (h>0),\) where \(B_2\) is a normalized parabolic spline with the uniform nodes and functionals \(y_j=y_j(

Isogeometric treatment of large deformation contact and debonding problems with T-splines: a review

open access: yesCurved and Layered Structures, 2015
Within a setting where the isogeometric analysis (IGA) has been successful at bringing two different research fields together, i.e. Computer Aided Design (CAD) and numerical analysis, T-spline IGA is applied in this work to frictionless contact and mode ...

Interpolação por splines cúbicos paramétricos no Maple para a segmentação do contorno do ventrículo esquerdo humano

open access: yesREMAT, 2016
O coração humano é dividido em quatro câmaras: átrio direito, ventrículo direito, átrio esquerdo e ventrículo esquerdo. Através de um incrível processo de sincronia elas recebem e impulsionam o sangue para ser oxigenado e para levar oxigênio a todas as ...

Automatic Generation of T-Splines with Extraordinary Points Based on Domain Decomposition of Quadrilateral Patches

open access: yesMathematics
Isogeometric analysis (IGA) is a numerical methodology for solving differential equations by employing basis functions that preserve the exact geometry of the domain. This approach is based on a class of mathematical functions known as NURBS (Non-Uniform

Comparison Between T-Spline Surface and NURBS Surface [PDF]

open access: yesEngineering and Technology Journal, 2015
This research uses T-spline for surface modeling and compares it with NURBS modeling to get the best modeling points between the two methods. The comparison will be through surface analysis and manufacturing process.T-Splines surfaces typically have 50 ...

Unified Representation of Curves and Surfaces

open access: yesMathematics, 2021
In conventional modeling, shared control points can be employed to realize a unified representation for an object consisting of only curves or only surfaces touching one another.

Multivariate Analysis-Suitable T-Splines of Arbitrary Degree

open access: yesComputational Methods in Applied Mathematics, 2023
Abstract This paper defines analysis-suitable T-splines for arbitrary degree (including even and mixed degrees) and arbitrary dimension. We generalize the concept of anchor elements known from the two-dimensional setting, extend existing concepts of analysis-suitability and show their sufficiency for linearly independent T-splines.

Transfinite Patches for Isogeometric Analysis

open access: yesMathematics
This paper extends the well-known transfinite interpolation formula, which was developed in the late 1960s by the applied mathematician William Gordon at the premises of General Motors as an extension of the pre-existing Coons interpolation formula. Here,
