Isogeometric Failure Analysis

2011
Isogeometric analysis is a versatile tool for failure analysis. On the one hand, the excellent control over the inter-element continuity conditions enables a natural incorporation of continuum constitutive relations that incorporate higher-order strain gradients, as in gradient plasticity or damage.

BDDC PRECONDITIONERS FOR ISOGEOMETRIC ANALYSIS

Mathematical Models and Methods in Applied Sciences, 2013
A Balancing Domain Decomposition by Constraints (BDDC) preconditioner for Isogeometric Analysis of scalar elliptic problems is constructed and analyzed by introducing appropriate discrete norms. A main result of this work is the proof that the proposed isogeometric BDDC preconditioner is scalable in the number of subdomains and quasi-optimal in the ...

Isogeometric Analysis for Electromagnetic Problems

IEEE Transactions on Magnetics, 2010
Isogeometric analysis (IGA) is a novel discretization method, introduced by Hughes, which is based on nonuniform rational B-splines (NURBS). Among other features, IGA uses directly the geometry description coming from computer-aided design software without approximation, and the analysis is performed using shape functions of variable (possibly high ...

Isogeometric analysis on triangulations

Computer-Aided Design, 2014
We present a method for isogeometric analysis on the triangulation of a domain bounded by NURBS curves. In this method, both the geometry and the physical field are represented by bivariate splines in Bernstein-Bezier form over the triangulation.

The Isogeometric Analysis Method

2023
The purpose of this book is to briefly present the ‘Method of Isogeometric Analysis’ which is an extension of the well-known Finite Element Method mainly with the extensive use of NURBS. Since 2008, i.e. three years after the first appearance of the method, many European research projects have been implemented and some of them have resulted in open ...
