Mechanical behavior of functionally graded material plates under transverse load—Part II: Numerical results

The formulations of the complete solutions to the rectangular simply supported plates with power-law, sigmoid, and exponential FGMs have been derived in Part I. In this part, we focus on the numerical solutions evaluated directly from theoretical formulations and calculated by finite element method using MARC program. The effects of loading conditions, the change of Poisson’s ratio, and the aspect ratio on the mechanical behavior of an FGM plate are discussed. Besides, a comparison of the results of P-FGM, S-FGM, and E-FGM is investigated.
