A three-dimensional stress analysis was performed on bonded pipeline repair joints for the current investigation. The present analysis has taken into account the influence of internal pressure circumstances, which are most frequently encountered during the flow of various fluids. The system's weakest link is typically its joints. In this study, one of the most frequent loading scenarios in piping systems internal pressure and tension is examined in relation to the response of various joint designs. The modeling and simulation approaches based on the finite element method that were created in this work are capable of carrying out a thorough examination of the three-dimensional stresses as well as a fracture analysis of the bonded joint. Software called ABAOUS was used to generate the numerical model. The stress concentrations as a function of different overlap lengths at and around the joints.
