PREDICTION OF TENSILE STRAIN CAPACITY FOR X52 STEEL PIPELINE MATERIALS USING THE EXTENDED FINITE ELEMENT METHOD

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
