Experiences with the isogeometric analysis in structural mechanics

Abstract eng:
The aim of this paper is to share with its readers the early experiences of its authors related to the implementation, use, and performance of the isogeometric analysis applied to two-dimensional linearly elastic problems. Isogeometric analysis has been recently introduced as a viable alternative to the standard, polynomial-based finite element analysis. Although the isogeometric analysis exhibits several interesting features and it has been shown that it can outperform the classical finite element method in many aspects, its way to the practical engineering is still at the beginning. Not only there are still many open issues that have to be solved but also rather different methodology has to get into awareness of engineering community currently tied up mostly to the finite element method.
