摘要
A method for material lifetime evaluation includes: causing a stress or a strain to be applied to a material surface based at least on a cycle of properties over time; causing an image of the material surface to be captured as a captured image; and determining a surface strain energy density (SSED) model for the material surface based at least on the captured image. A system for material evaluation includes: a load generator configured to apply a stress or a strain to a material surface based at least on a cycle of properties over time; a sensor configured to capture an image of the material surface as a captured image; and a processor configured to determine a SSED model for the material surface based at least on the captured image. In the method and the system the captured image is correlated to the cycle of properties.
