A series of photoelastic experiments were performed on finite width strips containing central holes with two equal radial cracks. Leads were applied through the pin having 1.6% clearance in the hole. Measurements. of maximum in-plane local shearing stress, $τ_max$ and orientation of maximum radius relative to crack plane, $Θ_m$ were made for progressively smaller fringes to solve stress-intensity factors, $K_I$ and $K_{II}$. Apparent stress-intensity factors were plotted along the distance from crack tip and extrapolated to the crack tip to yield the true values of $K_I$ and $K_{II}$ for various sheet-width to pin-diameter ratios and crack-length to sheet-width ratios. Photoelastic results were compared with finite element method results and compliance measurement results. Notch effects were examined and fracture path was predicted.
