Abstarct: In this study numerical and experimental analysis of fatigue crack growth in a plate under uniaxial loading . Numerical analysis of the research conducted using software Abaqus and the fatigue loading in this study, is simulated using the Paris law. The maximum tangential stress criterion to predict crack growth path is used. This criterion is the most comprehensive measure in the field. baxsed on this criterion, the crack growth direction is along the maximum tangential stress. Crack growth factors have been investigated by numerical analysis and Guidelines for the control of crack growth is expressed then The results of numerical analysis are compared with experimental results. This experimental study was conducted using a servo hydraulic 8802. Numerical and experimental results are close to each other well. Rectangular sheets, length and width of 100 mm and 150 mm respectively and material of sheet is St37 with a thickness of 2 mm and SS304 with a thickness of 0.9 mm and holes created in this plate is Circular shaped.
