A composite beam that exhibits variation of properties of a material which is created artificially as per a predefined function is a special category popularly termed as functionally graded beam. The notable part in such a variation in properties of material is that it can be in any of the three possibilities in any single, two dimensional direction or in all the three dimensional direction. It is quite possible to use the governing function in its standard or customized form as any researcher derives it. The nature of governing function of the properties of the graded beam is the reason behind the structural behaviour and the modal characteristic of a functionally graded beam as these two depends upon it. This research review focuses on a detailed examination of different governing equation which controls the variation of mechanical properties of a beam in different dimensional directions and their authority on structural and modal distinctiveness of the beam.

Vertical Gravity

In this study, glass-filled epoxy functionally graded material (FGM) was prepared by adopting the hand lay-up method. The vertical gravity casting was used to produce a continuous variation in elastic properties. A 30 % volume fraction of glass ingredients that have mean diameter 90 μm was spread in epoxy resin (ρ = 1050 kg/m3). The mechanical properties of FGM were evaluated according to ASTM D638. Experimental results showed that a gradually relationship between Young’s modulus and volume fraction of glass particles, where the value of Young’s modulus at high concentration of glass particles was greater than that at low concentration, while the value of Poisson’s ratio at high concentration of glass particles was lower than that at low concentration. The manufacture of this FG beam is particularly important and useful in order to benefit from it in the field of various fracture tests under dynamic or cyclic loads.

Gradient Variation

The objective of this paper is to investigate the large deflection of a slender functionally graded beam under the transverse loading. Firstly, by modeling the functionally graded beam as a layered structure with graded yield strength, a unified yield criterion for a functionally graded metallic beam is established. Based on the proposed yielding criteria, analytical solutions (AS) for the large deflections of fully clamped functionally graded beams subjected to transverse loading are formulated. Comparisons between the present solutions with numerical results are made and good agreements are found. The effects of gradient profile and gradient intensity factor on the large deflections of functionally graded beams are discussed in detail. The reliability of the present analytical model is demonstrated, and the larger the gradient variation ratio near the loading surface is, the more accurate the layer-graded beam model will be.
