... Abstract The ability to accurately estimate the tensile strain capacity (TSC) of a girth weld is critical to performing strain-based assessment (SBA). A wide range of geometry, material, and loading factors can affect the TSC of a girth weld. Among the influencing factors, an increase...

... Abstract Being able to estimate the tensile strain capacity (TSC) of vintage girth welds is sometimes necessary for the integrity management of vintage pipelines. Assessing girth weld integrity could be a top priority after a confirmed ground movement event. Decisions may also be needed about...

... the apparent CTOD R is demonstrated. The prediction of tensile strain capacity (TSC) using the CTOD A and the traditional tangent method is conducted. Similar results are obtained from both approaches. The value of apparent CTOD R is found to be relatively insensitive to the amount of flaw growth after some...

... 07 04 2011 Tensile strain capacity (TSC) is a critical component of the strain-based design of pipelines. TSC is affected by a number of material parameters, such as the strain hardening rate, weld strength mismatch, and toughness. Girth weld high-low misalignment, internal pressure...
