Isogeometric analysis of shells

, 2013
This work is concerned with the isogeometric analysis of shells. A new hierarchic family of NURBS-based shell finite elements is developed. Besides a shear-rigid 3-parameter shell element formulation with Kirchhoff-Love kinematics, both a shear flexible 5-parameter Reissner-Mindlin-type and a 7-parameter 3D shell element which accounts for thickness ...
