NURBS patch coupling with Nitsche's method for isogeometric analysis

摘要

To model geometrical entities with a certain complexity to be verified with isogeometric analysis (IGA) it is often necessary to use multi-patch. Nitsche's method allows the possibility of coupling the different patches even though the mesh at the interface is not conforming. Examples of three-dimensional models are analysed for linear static and modal analysis to validate the method.
