About the Influence of the Machined Defect Shape and Position on the Stress Distribution for Pipelines with Volumetric Defects
The aim of the paper is to analyse how the shape and position of the machined volumetric surface defects (VSD) may influence the stresses and displacements distributions for pipelines with VSD. The machined defect is usually rectangular, with edges oriented parallel/perpendicular to the pipe’s axis...

| Summary: | The aim of the paper is to analyse how the shape and position of the machined volumetric surface defects (VSD) may influence the stresses and displacements distributions for pipelines with VSD. The machined defect is usually rectangular, with edges oriented parallel/perpendicular to the pipe’s axis.
We attempt to analyse in this paper what happens when the machined defect is no longer rectangular, but circular or elliptical and with different positions relative to the pipe’s axis. We also consider different fillet radius of the machined VSD.
