The SIF decreases with the friction coefficient rising when the surfacecrack tip lies in the base and the reflective crack length is more than a certain value.
反射裂缝裂尖位于面层中且裂缝长度大于某一值时,应力强度因子随着摩擦系数的增加而减小。

By means of numerical calculation, the rules of J-Integral values varied with the length and depth of the inner surfacecrack of gun barrel were obtained.
通过数值计算,得出了身管内表面裂纹J积分值随裂纹长度及深度的变化规律。

It is obtained that the SIF increases with the length of the surfacecrack or the reflective crack enlarging in the asphalt pavement.
