摘要
提供了一个半解析权函数求解无量纲应力强度因子的方法,这对于求解诸如对径受压圆盘等一类应用问题有着重要的意义。计算了不同裂纹长度和不同裂纹倾角的巴西圆盘的Ⅰ型和Ⅱ型应力强度因子,并将半解析权函数法计算结果与其它文献所提供的结果进行了比较,发现吻合较好。
Calculation of the stress intensity factor is a crucial issue of fracture mechanics. This paper provides a semi-analytical weight function method to calculate the stress intensity factor, which is of interest for practical application (eg. diametral compression disk tests). The stress intensity factors, and of the Brazilian disks with variable angle and crack length are calculated by semi-analytical weight function method. By comparing the resulting of with the datum available in literatures, the good agreement has been obtained.
