Meanwhile, the influences of pipeline internalpressure, wall thickness, crack arrest length and initial crack velocity on the crack driving force (crack propagation) are further studied.
进而分析了管道内压、壁厚、裂纹止裂长度和初始裂纹速度对裂纹驱动力(也即裂纹扩展)的影响。

The stress distribution of a curved pipe with an initial elliptic cross section under internalpressure was studied by using electric resistance strain method.
