Also, the extrapolation method is used to obtain the SIF and stress triaxiality around the tip cracks. 应用外推法得到应力强度因子及裂尖周围的应力三维度。
Furthermore,through the example of computer programming,comparision of the formula precision which established Ang Adams extrapolation linear multistep method was made. 进一步通过实例运用计算机编程将阿达姆斯外推法等线性多步法和所建立的公式进行了精度比较。
