Reliability Based Design Framework for High Strength Linepipe

The internship objective is to establish a reliability based design framework for high strength linepipe subject to internal pressure, axial force and end moment for monotonic loading conditions. Linepipe grade material with specified minimum yield strength (SMYS) equal to or greater than Grade 550 (X80) is defined as high strength linepipe. The mechanical performance design criteria will be established through the development, calibration and validation of numerical modeling procedures such as finite element.
