Free vibrations and buckling analysis of laminated plates by oscillatory radial basis functions

Curved and Layered Structures, 2015
In this paper the free vibrations and buckling analysis of laminated plates is performed using a global meshless method. A refined version of Kant’s theorie which accounts for transverse normal stress and through-the-thickness deformation is used.
