“…Modelling of creep using a numerical calculation is required to predict the creep development which is then beneficial to evaluate the lifetime of the materials under creep conditions [3]. Implementing a finite element method using computer simulation has become a powerful tool to explore the creep behaviour of a material [7] [8]. Validated results between computational methods and experimental data can be used to further investigate several creep behaviours which may be difficult to be observed by experimental methods [9].…”

The Abaqus software was used to simulate the creep behavior of a cylindrical tube of Sanicro-25 austenitic steel under an internal pressure of 11.3 MPa at a uniform temperature at 750 °C. The data used for the simulation input were obtained from the experimental data of a previous work. The hidden information of material parameters was estimated from the shape of creep strain versus time plots obtained from the experimental data. The validated results between the simulation and the experimental data produced the material parameter of the creep power law which were set at 2.6 x 10-22 for the power law constant and 9 for the stress exponent. The parameters were further used to explore the stress and strain inside and outside of the tube wall and the thickness changes of the tube wall.
