Abstract Scope |
The objective of this research is to develop a finite element (FE) based model to predict the life of high-temperature alloys subject to the coupled thermomechanical fatigue (TMF)-creep condition. A unified viscoplasticity model is implemented using ANSYS to simulate the mechanical behaviors such as strain rate dependency, creep, and relaxation. The material parameters are calibrated in ANSYS TMF curve fitting tool based on the experimental isothermal strain control test data. After model calibration, the TMF-creep life is predicted using an Incremental lifetime model implemented in Ansys ACT. |
