Abstract:
A method of determining when a component exceeds a predetermined stress level that is less than a fatigue failure level for the component comprising providing a braze joint in a high stress area of a target component, the braze joint designed to accommodate stress/strain up to the predetermined threshold level; measuring strain at the braze joint; observing a shift in strain indicative of a failed brazed joint; utilizing information obtained to repair, replace or set a remaining service life for the target component.
