Blended Isogeometric Shells

Abstract

We propose a new isogeometric shell formulation that blends Kirchhoff-Love theory with Reissner-Mindlin theory. This enables us to reduce the size of equation systems by eliminating rotational degrees of freedom while simultaneously providing a general and effective treatment of kinematic constraints engendered by shell intersections, folds, boundary conditions the merging of NURBS patches, etc.We illustrate the blended theory's performance on a series of test problems.
