Keywords: Shape optimization Isogeometric analysis Sensitivity analysis Free-form shells Rotation-free Shape optimization benchmark a b s t r a c t We present isogeometric shape optimization for shell structures applying sensitivity weighting and semi-analytical analysis. We use a rotation-free shell formulation and all involved geometry models, i.e.,(More)
We present different innovative formulations for shear deformable beams and plates exploiting the high inter-element continuity provided by NURBS basis functions. We develop isogeometric collocation methods in standard and mixed formulations as well as Galerkin methods using an alternative set of discrete variables. All methods are free of shear locking,(More)
