The paper analyses the stress distribution in an isotropic plate with a rectangular opening, subjected to tensile loads. The presence of such opening shape typically has a negative effect on the magnitude and distribution of stresses in parts of mechanical structures, that can influence their safety and reliability, and also has a negative impact on their service life. Hence, special attention is devoted to designing and manufacturing of parts that contain such openings. Thus, the effects of the presence of rectangular openings in parts of plates subjected to tension in two perpendicular directions is analysed. Analytical and numerical methods are used, and the materials are assumed to be isotropic.
