  Functionally graded porous (FGP) plates have been introduced as modern
structural members which open a new window to optimal and functional designs.
Despite the need to study the effect of graded porosity on the mechanical
behavior of FGP plates, it is necessary to consider the very extensive and
valuable literature in this field, presenting remarkable closed-form solutions.
Hence, this paper aims to answer where is possible to implement the available
exact solutions for the analysis of FGP plates. As the special distinction of
FGP plates, graded porosity, is reflected in their stiffnesses and moments of
inertia coefficients, 12 different functionality of porosity distribution along
the thickness are considered and a set of explicit formulation for evaluating
these coefficients are presented to be substituted in already provided
analytical solutions. Many examples including bending and free vibration of
thin and thick FGP plates are exhibited and the influence of the type of
porosity distribution is discussed in details. This work can be considered as a
guideline for designers to evaluate the effect of graded porosity based on the
cornerstone of the huge number of solutions in the precious literature of plate
theories.
