We say that [LAMBDA] is a generalized differential quotient (GDQ
) of F at ([bar.x], [bar.y]) in the direction S, and write [lambda] [member of] GDQ(F, [bar.x], [bar.y], S) if for every positive real number [delta] there exist U;G such that

[14-16] studied the dynamic behavior of functionally graded or laminated composite doubly curved shells and panels of revolution by using the Generalized Differential Quadrature (GDQ
Ebrahimi and Najafizadeh  used the methods of generalized differential quadrature (GDQ
) and generalized integral quadrature (GIQ) to study the free vibration of a two-dimensional functionally graded circular cylindrical shell based on Love's first approximation classical shell theory.

 considered the static and dynamic analyses of laminated doubly curved and degenerate shells and panels on the Winkler and Pasternak foundations by using the generalized differential quadrature (GDQ
) method and FSDT.
Tornabene and Viola  proposed an approach to analyse free vibration of parabolic shells using Generalised Differential Quadrature method (GDQ
) based on the first-order shear deformation theory.
