A simple FSDT-based isogeometric analysis for geometrically nonlinear analysis of functionally graded plates
A novel and simple FSDT-based isogeometric analysis for geometrically nonlinear analysis of FGM plates is presented. A new simple first-order shear deformation plate theory is used. The effects of boundary conditions, gradient index, length-to-thickness ratio, etc. on geometrically nonlinear responses of plates are investigated. The proposed approach with several advantages is effective, highly accurate, free of shear-locking, etc. in geometrically nonlinear analysis.
