Vibration Analysis of Rectangular Plates with Free Corners Using Spline-Based Differential Quadrature

open access: yesShock and Vibration, 2004
A spline-based differential quadrature method (SDQM) is elaborated and applied to the vibration analysis of rectangular plates with free edges. The sextic B-spline functions are used to construct the pertaining cardinal spline interpolants.

Planar cubic Cardinal spline with tension parameter and boundary condition optimization(优化张力参数与边界条件的平面三次Cardinal 样条)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2019
当数据点给定时,三次Cardinal 样条的张力参数和边界条件均为自由变量,因此可对这些自由变量进行优化,以得到满足某种特定要求的最佳三次Cardinal 样条。讨论了如何通过优化张力参数与边界条件使得构造的平面三次Cardinal 样条尽可能光顺。首先,分析了三次Cardinal 参数样条曲线形状的影响因素;然后,利用曲率变化能极小对三次Cardinal 参数样条曲线的张力参数与边界条件进行优化,获得张力参数与边界条件的唯一解; 最后,给出了对应三次Cardinal ...

Polyhyperbolic Cardinal Splines [PDF]

open access: yes, 2017
In this note we discuss solutions of differential equation $(D^2-α^2)^{k}u=0$ on $\mathbb{R}\setminus\mathbb{Z}$, which we call hyperbolic splines. We develop the fundamental function of interpolation and prove various properties related to these splines.

Isogeometric Transfinite Elements: A Unified B-Spline Framework for Arbitrary Node Layouts

open access: yesAxioms
This paper presents a unified framework for constructing partially unstructured B-spline transfinite finite elements with arbitrary nodal distributions. Three novel, distinct classes of elements are investigated and compared with older single Coons-patch

Cardinal interpolation by multivariate splines [PDF]

open access: yesMathematics of Computation, 1987
The purpose of this paper is to investigate cardinal interpolation using locally supported piecewise polynomials. In particular, the notion of a commutator is introduced and its connection with the Marsden identity is observed. The order of a commutator is shown to be equivalent to the Strang and Fix conditions that arise in the study of the local ...

Cardinal interpolation and spline functions. III. Cardinal Hermite interpolation

open access: yesLinear Algebra and its Applications, 1973
AbstractThe results of item [9] in our list of References, concerning cardinal spline interpolation of data of power growth are here extended to the case of Hermite interpolation. Let m ⩾2, and 1 ⩽γ⩽m. Given are now γ sequences y = (yν), y′ = (yν′),…,y(r−1) = (yν(r−1)) (− ∞ < ν < ∞), and the objective is to find a cardina spline function S(x) of degree
