Abstract
In this paper an improved theoretical interfacial stress analysis is presented for simply supported beam bonded with a FG plate. This solution take into account the dislocation of the neutral axes and this is helpful for introducing the inhomogeneity through the thickness of the plate and thus this solution is applicable for wide range of composite material. The plate is assumed to be isotropic with a constant Poisson’s ratio and variation according to a power law for the elastic modulus through the plate thickness. Stresses distribution are presented in form of graphs, it is shown that both normal and shear stresses at the interface are influenced by the inhomogeneities due to the variation in mechanical characteristics or porosity distribution, also the geometric of the plate play an important role in the distribution of interfacial stresses. This research is helpful in understanding the mechanical behavior of the interface and strengthened structure instability. The results presented in the paper can serve as a benchmark for future analyses of bonded beams with composite plate.
