The study of the stress concentration factor for rectangular composite plates with geometrical discontinuities become essential due to the their extensive practical applications in different fields of engineering. The aim of this work is to contribute in the understanding of the behavior of stress concentration factor around hole in orthtropic plate while considering the effect of some paramters on the SCF. A numerical investigation based on a two-dimensional finite element approach is carried out using Abaqus. Indeed, the effect of the fiber orientation, stacking sequence and the hole size on the SCF is determined for the plate with circular hole subjected to unidirectional loading. As well as, the influence of the axis ratio of the elliptical hole with the loading's direction on the SCF and the stress distribution are shown.
