Treatment of ReissnerMindlin shells with kinks without the need for drilling rotation stabilization in an isogeometric framework
An isogeometric ReissnerMindlin shell formulation which is able to handle complex intersections with kinks is presented. The proposed framework allows the omission of drilling rotation stabilization. An automatic distinction method for the quantification of rotational degrees of freedom for every node is presented. Two concepts for the description of rotations are presented and compared.
