    摘要:

    给出了一个计算三点弯曲圆梁试样的稳定性因子的方法,并将计算结果与其它试样进行了比较。

    Abstract:

    Crack growth stability is very important for fracture toughness testing of brittle materials. The width of crack for a three-point bend round beam specimen changes continuously during the process of crack extension, so that the analysis of crack growth stability becomes complicated for this kind of specimen. This paper presents a method for calculating its stability factors, and the results of the calculation are compared with those of other specimens.
