Extended isogeometric analysis based on Bézier extraction for an FGM plate by using the two-variable refined plate theory

The static and dynamic analysis for the functionally graded material (FGM) plate is performed by using the extended isogeometric analysis (XIGA) based on the Bézier extraction and two-variable refined plate theory (RPT). The two-variable RPT using only four parameters for the displacement fields overcomes the shear locking without the shear correction factor. The isogeometric analysis (IGA) reduces the computational cost by avoiding multiple...
