Prediction of Tensile Strain Capacity for X52 Steel Pipeline Materials Using the Extended Finite Element Method
Strain-based design (SBD) plays an important role in pipeline design and assessment of pipelines subjected to geo-hazards.Under such hazards, a pipe can be subjected to substantial plastic strains, leading to tensile failure at locations of girth weld flaws.For SBD, the finite element method (FEM) can be a reliable tool to calculate the tensile Tot
