In-plane material inhomogeneity of functionally graded plates: A higher-order shear deformation plate isogeometric analysis

Numerical investigation of buckling and free vibration of functionally graded plates considering in-plane material inhomogeneity is presented in this paper. A novel and effective approach based on isogeometric analysis (IGA) and higher-order shear deformation theory (HSDT) is developed for fulfilling that purpose, analyzing the critical buckling parameter and natural eigenvalues of functionally graded plates involving the in-plane material...
