This chapter is devoted to the investigation of a damaged pipeline segment with two volumetric surface defects (VSDs) located on the outer or inner surfaces. The segment was subjected to static inner pressure in the linear elastic domain, since when stresses go beyond this limit the defect is no longer accepted. The main attention is focused on the interaction between these two defects and on how this interaction influences the stress–strain state in the pipeline segment. Moreover, the problem with two volumetric surface defects was divided into two cases. First, when defects are not repaired at all. Second, when composite wrap was applied in the damaged zone. In order to solve these problems, series of computational experiments were performed with the help of finite element modeling using ANSYS and Siemens NX packages.
