- 論文の詳細を見る
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 notch, several bending moments were applied. Similar to the experimental results in tension, the stress concentration factor is the larger, the smaller the root radius, its variation being extremely steep for the values of ρ/b less than 0.3. The included angle has a little influence in the region between 0° and 90°, and as it exceeds 90°, the stress concentration factor diminishes gradually. The depth of notch has such an effect as to give the stress concentration factor its maximum value when the value of t/b is nearly 0.15 to 0.25.
