Extended isogeometric analysis based on Bézier extraction for the buckling analysis of Mindlin–Reissner plates

In this paper, the buckling analysis for the Mindlin–Reissner plates is performed by applying the isogeometric analysis (IGA) coupled with Bezier extraction operator. The Bezier extraction operator allows the incorporation of non-uniform rational B-spline-based IGA into the existing finite element method (FEM) work frame. For cracked plates, the extended IGA (XIGA) is employed. Unlike previous FEM approaches, the present method is expected to be...
