A calculation method for limit load of the gas pipelines with girth weld surface cracks
In this paper, a finite element model with girth weld defects considering crack tip singularity was established in order to facilitate the accurate and rapid safety assessment on girth weld defects of long distance gas Transmission pipeline. Then the J-integral of girth weld cracks in pipes with dif...
