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)
This paper presents an effective method to perform Code Verification of a software which is designed for structural analysis using membranes. The focus lies on initially curved structures with large deformations in steady and unsteady regimes. The material is assumed to be linear elastic isotropic. Code Verification is a part of efforts to guarantee the(More)
