- Abstract
- The paper presents the developed model for predicting the behavior of a ferritic-martensitic steel during all creep stages. A modified θ-projection method is proposed as a solution. The main advantages of the method are abilities to model creep curves for a wide range of temperatures and stresses (which reduces the need for long-term run tests); to validate calculations by determining time to failure; to predict a steadystate creep rate. Despite the usefulness of the proposed approach, certain limitations are noted that result in modeling uncertainties. Higher accuracy and robustness can be achieved using a "mechanical equation of state equation" model of Rabotnov type.
