Higher‐Order, Mixed‐Hybrid Finite Elements for Kirchhoff–Love Shells
International Journal for Numerical Methods in Engineering, Volume 126, Issue 21, 15 November 2025.ABSTRACT A novel mixed‐hybrid method for Kirchhoff–Love shells is proposed that enables the use of classical, possibly higher‐order Lagrange elements in numerical analyses. In contrast to purely displacement‐based formulations that require higher continuity of shape functions as in isogeometric analysis (IGA), the mixed formulation features ...

Algebraic Point Projection for Immersed Boundary Analysis on Low Degree NURBS Curves and Surfaces
Algorithms, 2020 Point projection is an important geometric need when boundaries described by parametric curves and surfaces are immersed in domains. In problems where an immersed parametric boundary evolves with time as in solidification or fracture analysis, the ...

IGA-based Multi-Index Stochastic Collocation for random PDEs on arbitrary domains
, 2019 This paper proposes an extension of the Multi-Index Stochastic Collocation (MISC) method for forward uncertainty quantification (UQ) problems in computational domains of shape other than a square or cube, by exploiting isogeometric analysis (IGA ...

Unstructured grids on NURBS surfaces [PDF]
11th Applied Aerodynamics Conference, 1993 A simple and efficient computational method is presented for unstructured surface grid generation. This method is built upon an advancing front technique combined with grid projection. The projection technique is based on a Newton-Raphson method. This combined approach has been successfully implemented for structured and unstructured grids.

Advanced Engineering Materials, Volume 27, Issue 22, November 2025.Cubic Bézier curves are used in the synthesis of novel surface‐based metamaterials with tunable mechanical properties. Surface‐based geometries are 3D printed and tested in compression. The resulting mechanical properties are correlated to changes in the shape of the base curve, with high potential in energy absorption through the adjustment of their ...

Fitting and fairing quad-meshes by matrix weighted NURBS surfaces(矩阵权NURBS曲面的拟合与光顺)
Zhejiang Daxue xuebao. Lixue ban, 2023 介绍了利用矩阵权非均匀有理 B-spline（non-uniform rational B-spline，NURBS）曲面拟合与光顺带法向的网格数据。通过输入带法向的规则四边形网格，以网格的顶点为曲面的控制顶点，用法向信息计算每个控制顶点对应的矩阵权，构造矩阵权NURBS曲面。与传统NURBS曲面相比，矩阵权NURBS曲面具有拟柱面精度，当数据均匀采样自光滑曲面时，构造的矩阵权NURBS曲面具有较好的光顺性且能很好地拟合网格模型；当输入的网格数据掺杂噪声时 ...

The Anatomical Record, Volume 308, Issue 11, Page 2962-2975, November 2025.Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐
