| Abstract: | A formula for calculating K1 of a V-notched beam under arbitrary span three points bending is given by the use of superposition techniques. This formula gives a theoretical basis for the calculation of applied load in bar stress severing method. |
| Keywords: | arbitrary span three points bending four points bending stress intensity factor V-notch specimen superposition principles loading method force of loading |
