In this sudy, a simply supported FGM plate-strip with rectangular hole subjected
to bending loadings is investigated. Young’s modulus varies continuously
throughout the length and width of the plate-strip based on the power-law
functions; but the Poisson's ratio and material density are assumed to be constant.
The classical linear elasticity theory and the generalized plane-strain conditions are
assumed for the modelling of the theoretical investigations. The solution of the
considered problem is obtained numerically with the help of the Finite Element
Method (FEM). Finite number of sub-domains (FEs) are used for the discretization
of the solution domain and the solution in each sub-domain is considered as a
polynomial function. Employing the Ritz technique, the FEM modelling of the
boundary value problem is obtained. The solution domain is discretized a certain
number of rectangular elements having nine nodes. We have used displacementbased finite elements for the FEM modelling. The solutions of the displacement
and stress concentration are investigated to understand the hole effect on the platestrip made of functionally graded materials.
