چکیده
Strain-based design (SBD) plays an important role in pipeline and assessment of pipelines subjected to geo-hazards. Under such hazards, a pipe can be substantial plastic strains, leading tensile failure at locations girth weld flaws. For SBD, the finite element method (FEM) reliable tool calculate strain capacity (TSC) for better pipelines. This study aims investigate ductile fracture properties specific vintage steel (API 5L grade X52) using extended (XFEM). Eight full-scale tests were simulated commercial analysis software ABAQUS Version 6.17. Maximum principal is used assess damage initiation cohesive zone model (CZM) when crack evolution evaluated by energy release. A proper set parameters X52 materials was calibrated based on ability reproduce experimental results. These results included strain, applied load, endplate rotation, mouth opening displacement (CMOD). describes methodology validation XFEM required propagation grades pipeline.

متن کاملFailure Prediction during uniaxial Superplastic Tension using Finite Element Method
Superplastic materials show a very high ductility. This is due to both peculiar process conditions and material intrinsic characteristics. However, a number of superplastic materials are subjected to cavitation during superplastic deformation. Evidently, extensive cavitation imposes significant limitations on their commercial application. The deformation and failure of superplastic sheet metals...
