Development and Implementation of NURBS Models of Quadratic Curves and Surfaces [PDF]
, 2009 This article goes into the development of NURBS models of quadratic curves and surfaces. Curves and surfaces which could be represented by one general equation (one for the curves and one for the surfaces) are addressed. The research examines the curves:

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 ...

A novel updating modelling methodology for free-form surface modifications in the early stages of design [PDF]
, 2003 The paper describes the first implementation of a method in which an initial CAD model is updated from a physical model. The method is based on image-mapping in which an initial CAD model is updated from images of a soft rapid prototype model (RPM) which

Isogeometric Analysis and Harmonic Stator-Rotor Coupling for Simulating Electric Machines
, 2017 This work proposes Isogeometric Analysis as an alternative to classical finite elements for simulating electric machines. Through the spline-based Isogeometric discretization it is possible to parametrize the circular arcs exactly, thereby avoiding any ...

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 ...

An experimental study to test a 3D laser Scanner for body measurement and 3D virtual garment design in Fashion education [PDF]
, 2005 Artists, scientists, anthropometrists and tailors have accurately measured the human body with traditional tools, such as tape measures, callipers and accumulated visceral experience for centuries. Due to the progressive acceleration in the quality of 3D

A segmentation-free isogeometric extended mortar contact method
, 2018 This paper presents a new isogeometric mortar contact formulation based on an extended finite element interpolation to capture physical pressure discontinuities at the contact boundary. The so called two-half-pass algorithm is employed, which leads to an

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‐
