- Evaluation of Stress Concentration Factor for a Double-Notched Plate
この論文をさがす
抄録
The stress concentration factor is an important parameter for evaluation of the strength of notched materials and critical stress at crack initiation of notched materials. The value of the stress concentration factor is determined according to the geometry of the notched materials. In the present study, to understand the evaluation method of the stress concentration factor for double-notched specimens, a series of double-notch patterns has been developed and computed by the body force method. For the calculation, a double notch was positioned at the edges of the calculation model of a finite plate under tensile stress and the double notch was symmetrical with the center axes of the calculation model. The effect of the shape of the second notch which was cut at the notch bottom of the first notch on the value of the stress concentration factor was examined, and the evaluation method of the stress concentration factor of a double-notched plate with finite width is discussed. Care was taken that the second notch size was relatively smaller than that of the first notch due to considerations of the applicability of the double-notch concept and the equivalent notch concept.
