Kurzfassung
The idea of isogeometric analysis is to use the more sophisticated basis functions of design systems alsofor the analysis. This requires a thoughtful update of element formulations. A precise and effective Reissner–Mindlinshell formulation is presented in this contribution. Special focus is put on the numerical integration of the stiffnessmatrix. The usage of non-uniform integration can have positive or negative effects on the accuracy of computations.A numerical example assesses the interaction between rotational concepts and integration.
