Enhancing SfePy with Isogeometric Analysis

CoRR, 2014
In the paper a recent enhancement to the open source package SfePy (Simple Finite Elements in Python, http://sfepy.org) is introduced, namely the addition of another numerical discretization scheme, the isogeometric analysis, to the original implementation based on the nowadays standard and well-established numerical solution technique, the finite ...

ISOGEOMETRIC FE ANALYSIS OF COMPLEX THIN-WALLED STRUCTURES [PDF]

, 2015
Isogeometric analysis, as a special field of the finite element method (FEM) which integrates geometric and finite element mesh modelling, is one of the promising directions of FEM development. The paper presents a concept of isogeometric FEM analysis of

Isogeometric level-set topology optimization for the design of geometrically nonlinear auxetic metamaterials with AM experimental analysis

Materials & Design
Auxetic metamaterials have garnered significant attention in advanced industrial manufacturing due to their superior mechanical properties, which are characterized by a counterintuitive Negative Poisson’s Ratio (NPR).

Transfinite Patches for Isogeometric Analysis

Mathematics
This paper extends the well-known transfinite interpolation formula, which was developed in the late 1960s by the applied mathematician William Gordon at the premises of General Motors as an extension of the pre-existing Coons interpolation formula. Here,

Isogeometric Analysis

, 2010
NURBS (Non Uniform Rational B-Spline) curves and surfaces have been used extensively in Computer Aided Design (CAD) in the last two decades but not in Finite Element Analysis (FEA). Isogeometric analysis [6], introduced in 2005 by Hughes [9] proposes to replace traditional Finite Elements with volumetric NURBS.

ISOGEOMETRIC STRUCTURAL ANALYSIS BASED ON NURBS SHAPE FUNCTIONS

Facta Universitatis. Series: Mechanical Engineering, 2014
Finite element method (FEM) is a tool that is mostly used for the structural analysis. The method is based upon approximation of the actual geometry and displacement field of the structure over the finite element domain.

Isogeometric analysis for anti-plane fracture problems

, 2013
We present an Isogeometric Analysis study of for the strain gradient fracture problem. In particular we consider an anti-plane formulation (Mode III). The numerical approximation we resort to a standard Galerkin isogeometric formulation and the results ...
