A Novel Mixed‐Hybrid, Higher‐Order Accurate Formulation for Kirchhoff–Love Shells
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT This paper presents a novel mixed‐hybrid finite element formulation for Kirchhoff–Love shells, designed to enable the use of standard C0$C^0$‐continuous higher‐order Lagrange elements. This is possible by introducing the components of the moment tensor as a primary unknown alongside the displacement vector, circumventing the need for C1$C^1 ...

Interactive rendering of NURBS surfaces [PDF]
Computer-Aided Design, 2014 [Resumo] As superficies NURBS (Non-uniform rational B-splines) son unhas das primitivas más empregadas no modelado de alta calidade nas ferramentas CAD/CAM e o software gráfico. Dado que a avaliación directa de superficies NURBS na GPU é unha tarefa altamente complexa, a aproximación máis común para o render de NURBS é a súa conversión previa na CPU en
