Özet:    In this study, the effect of initial stresses on the stress state of a plate-strip made of functionally graded material (FG) under bending is investigated. It is assumed that the initial stresses in the plate-strip are made by the uniformly distributed force acting on the two opposite sides of this plate-strip before the main loading. Then, the problems of determining the stress concentration in the structure due to bending of this plate acting the uniformly distributed  force on the upper face-plane of the FG plate are modeled by using the Linearized Three-Dimensional Elasticity Theory under the assumption of plane strain state. The solutions of the considered boundary value problems are solved numerically by using the Finite Element Method. In the investigations, the change of the Young's modulus of the FG plate-strip material in the direction of the coordinate axes are chosen as a polynomial function, but the Poisson's ratio and material density are assumed to be constant.
