Micro Abstract:
Two novel hierarchic isogeometric formulations for geometrically nonlinear shell analysis including transverse shear effects are presented. Both concepts combine a fully nonlinear rotation-free Kirchhoff-Love shell model with hierarchically added linearized transverse shear components. An additive split of Green-Lagrange strains dramatically facilitates representing large rotations in shell analysis while the proposed hierarchic concepts are intrinsically free from transverse shear locking.
