Download or read book Isogeometric analysis and hierarchical refinement for multi-field contact problems written by Dittmann, Maik and published by KIT Scientific Publishing. This book was released on 2017-03-20 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work deals with multi-field contact problems in the context of IGA. In particular, a thermomechanical as well as a fracture mechanical system is considered, where novel formulations are introduced for both. The corresponding discrete contact formulations are based on a variationally consistent mortar approach adapted for NURBS discretized and hierarchical refined surfaces. Finally, the capabilities of the proposed framework are demonstrated within numerous numerical examples.
