摘要：A method of forming a passive strain indicator on a preexisting component

includes directly depositing a plurality of fiducial markers on a portion of the outersurface of the preexisting component, the fiducial markers including a material that iscompatible with the material of the outer surface. A method of evaluating a componentincludes initially scanning a plurality of fiducial markers on a portion of an outer surfaceof the component, subjecting the component to at least one duty cycle, subsequentlyscanning the plurality of fiducial markers after the at least one duty cycle, measuring adisplacement of the plurality of fiducial markers by comparing the subsequent scan tothe initial scan, and determining a remaining usable life of the component by looking upin a database a predetermined value of the remaining usable life of the componentcorresponding to the measured displacement of the plurality of fiducial markers.
