Flat bar specimens of Phenolite with V notches on both edges were subjected to pure bending and the stress concentration factors under various conditions were measured by the photoelastic method. To determine the fringe orders at the base of the notch, several bending moments were applied. The effects of the root radius, the notch angle and the depth of the notch on the magnitudes of stress concentration factor were investigated. Experimental values were compared with Neuber's theoretical values and Nishida's experimental values with a single notch. The results obtained were as follows : (1) As to the effect of the root radius, stress concentration factor decreases steeply until ρ/♭ is nearly 0.3, and thereafter its diminution becomes rather slow. (2) The effect of the variation of the notch angle is little until the notch angle reaches 90°. For the value of the notch angle larger than 90°, the stress concentration factor decreases gradually till it reaches unity. (3) With respect to the effect of the depth of the notch, the stress concentration factor has its maximum value when τ/♭ is 0.15 to 0.25. (4) In all cases, the experimental values obtained were smaller than Neuber's theoretical ones.
