Improved numerical integration for locking treatment in isogeometric structural elements, Part I: Beams

A general mathematical framework is proposed, in this paper, to define new quadrature rules in the context of B-spline/NURBS-based isogeometric analysis. High order continuity across the elements within a patch turned out to have higher accuracy than C0 finite elements, as well as a better time effi...
