Quadratic NURBS-based discretizations of the Galerkin method suffer from membrane
locking when applied to Kirchhoff–Love shell formulations. Membrane locking causes not …

We present an open Octave/Matlab package nligaStruct, for linear and nonlinear
isogeometric analysis of thin-walled structures. nligaStruct is an extension of NLIGA in …

In this article, we study the effect of small-cut elements on the critical time-step size in an
immersogeometric explicit dynamics context. We analyze different formulations for second …

In order to perform isogeometric analysis with increased smoothness on complex domains,
trimming, variational coupling or unstructured spline methods can be used. The latter two …

A novel approach of polygonal scaled boundary isogeometric analysis is proposed for 2D
elasticity problems involving trimmed geometries. The method addresses the challenge of …

Penalty methods have proven to be particularly effective for achieving the required C 1-
continuity in the context of multi-patch isogeometric Kirchhoff–Love shells. Due to their …

This publication presents required steps for the realization of the pre-and post-processing for
the isogeometric analysis and the isogeometric B-Rep analysis, with a focus on the …

We propose a convenient methodology for the modeling and analysis of aircraft compressor
blades. To meet this goal, IsoGeometric Analysis is put to good use, as it allows for an exact …

In the aerospace field, there are numerous assembled thin-walled structures with complex
geometric continuity conditions. This makes isogeometric analysis (IGA) inevitably meet …

This work focuses on the coupling of trimmed shell patches using Isogeometric Analysis,
based on higher continuity splines that seamlessly meet the C 1 requirement of Kirchhoff …
