Stress concentrations around holes have great practical importance during the design of mechanical structures. This phenomenon is the main cause of failure. In addition, crack initiation happens near the stress concentration region. In this paper, the work is carried out to analyze the stress concentration, around two circular holes in orthotropic rectangular plates, subjected to tension load by using finite element method. Several parameters were considered such as the orientation of the fibers, the mechanical characteristics of the composites and the distance between holes.
