This project will define a general approach to, and advance development of, a useful predictive computer-modeling tool for analyzing failure modes of cladded materials used in oil and gas operations. It will develop and validate a constitutive model to define fatigue and fracture behavior of cladded pipe under deep-water conditions. The failure prediction tool will predict fatigue and fracture performance of cladded weld materials in equipment used in high pressure (15 ksi) and high temperature (>350℉) (HPHT), corrosive environment (H2S, Cl, S and CO2).
