Geometrically nonlinear isogeometric analysis of functionally graded plates based on first-order shear deformation theory considering physical neutral surface

This paper presents the geometrically nonlinear isogeometric analysis of functionally graded material (FGM) plates based on the first-order shear deformation theory considering the physical neutral surface. According to the power law distribution of volume fraction of constituents, the material properties of plate are assumed to vary through the thickness. The transverse shear correction factor is evaluated through the energy equivalence and the...
