New Applications of Isogeometric Methods to Structural Analysis
organised by Prof. M. Cuomo, Dr L. Greco
University of Catania, Italy
and Prof. A. Reali
University of Pavia, Italy
Session Aims and Scope
Isogeometric Analysis (IGA) is a recently developed computational approach that offers the possibility of integrating FEA into conventional NURBS-based CAD design tools. Currently, it is necessary to convert data between CAD and FEA packages, a difficult task since the underlying geometric description is different for CAD and FE codes. IGA employs typical basis functions of CAD packages (such as, e.g., B-Splines or NURBS) as a basis for FEA, within an isoparametric approach. Non-Uniform Rational B-Splines (NURBS), or more in general other functions employed in CAD systems, are thus used as basis functions for the approximation of both the geometrical model and the unknown variables of the structural model (e.g., displacements). Therefore, IGA formulations are commonly based on splines of high polynomial degrees, allowing to obtain a high internal parametric continuity of the solution, which has been proven to provide more possibilities and advantages with respect to standard high-order FEA.

Current research on IGA includes applications to structural models as thin shells, rods, light membranes, where it has shown several advantages over traditional FEA, as well as to the analysis of fluid-structure interaction, modeling of discontinuous fields, like in fracture mechanics, local and non-local analysis of continuous bodies, etc. An important research topic within the IGA context is the implementation of multi-patch methods with high inter-patch continuity properties.

This minisymposium aims at bringing together researchers, with backgrounds in different fields, who are currently working on IGA, in order to share experiences and discuss possible solutions and new approaches.
