The photoelastic stress-freezing method is applied to determine the stress concentrations around circular holes in flat plates, reinforced by rings with fillets which are symmetrically placed with respect to the plates, under uniaxial tension. The investigation is performed on the rings of different proportions and on the fillets of various radii of curvature, and the three dimensional effects of reinforcements on the stress concentrations around the circular holes are examined. Both the effective height of the reinforcing ring and the minimum radius of curvature of the fillet effective in reducing the stress concentration in a perforated plate are studied in connection with the optimum reinforcement.}, pages = {177--196}, title = {Photoelastic analysis of the maximum stress in a plate with a reinforced circular hole under uniaxial tension}, volume = {19}, year = {1968} }
