Abstract:
A method for material lifetime evaluation includes: causing a stress to be applied to a material surface of a component based at least on a cycle of load properties over time; causing an image of the material surface to be captured as a captured image of a complete in-situ field; determining an area of a hysteresis of a stable surface strain region in a stress-strain curve of the material surface to determine a loss energy (first damage parameter) for low cycle fatigue modeling; determining a deformation energy (second damage parameter) for high cycle fatigue monitoring; determining a failure parameter based on at least one of the first damage parameter and the second damage parameter; comparing the failure parameter to a record in a database; and determining a remaining life of the component based on comparison of the failure parameter to the record in the database.
