【 摘 要 】

AbstractThe aim of this paper is to study the effect of functionally graded material (FGM) layer around a notch in a plate in three dimensions. Using exponential law of variation of Young's modulus and a coefficient of Poisson constant, the stress concentration factor (SCF) depends on the gradation direction of the constituent materials. The finite element method is used to study the performance of FGM layer around a notch in a ceramic plate under in tensile load. A parametric study is performed for several geometric and mechanical parameters such that width of the FGM layer and the ratio of FGM layer components. The effect of notch radius is also studied.
