In the present paper, the first-order shear deformation plate (FSDT) model is exploited
to investigate the mechanical behavior of laminated composite and functional graded plates. Three
approaches are developed to transform the laminated composite plate, with stepped material properties,
to an equivalent functionally graded (FG) plate with a continuous property function across
the plate thickness. Such transformations are used to determine the details of a functional graded
plate equivalent to the original laminated one. In addition it may provide an easy and efficient way
to investigate the behavior of multilayer composite plates, with direct and less computational
efforts. A comparative study has been developed to compare the effectiveness of the three proposed
transformation procedures.
