Creep life estimation using Finite Element analysis

Advances have been made in the use of Finite Element (FE) simulation techniques to estimate the creep failure life of components operating at high temperature. The High Temperature Performance (HTP) Research Group at the University of Nottingham has developed new continuum damage mechanics approaches for predicting the creep damage in and around pipe welds.

The experimental test data supplied by the WELDON industrial partners have been used to create creep constitutive laws that were used to predict the damage and rupture life of pressurised pipes. The continuum damage approach will be extended to deal with other types of welds used in high temperature pipe applications. The work has resulted in several publications in international journals and conferences.
