Abstract
A method of making a component with an integral strain indicator includes forming the component from a first material, where the component has an outer surface and an internal volume; and directly depositing a plurality of fiducial markers on a portion of the outer surface. The fiducial markers are formed from a second material that is compatible with the first material, and the portion of the outer surface defines an analysis region on the outer surface of the component. The analysis region defines a gage length, and each fiducial marker of the plurality of fiducial markers has a maximum diameter of between one-tenth and one-twentieth of the gage length. Periodic measurement of the fiducial marker positions is performed to monitor component strain.
