Abstract
Abstract. In this work, the isogeometric concept is applied to the analysis of shell structures. A rotation-free element is developed, using the Kirchhoff-Love theory and NURBS as basic functions. An analysis based on NURBS provides advantages especially for shells, since the structural behavior of a shell is mainly determined by its geometry and therefore a good description of the geometry is essential. In addition, due to the exact description of the geometry with NURBS, the curvatures can be evaluated directly on the surface without rotational degrees of freedom. Different examples show the good performance and precision of the method, for problems with geometric linearity.
