Passive strain indicator
First Claim
1. A method of making a component with a passive strain indicator, the method comprising:
- forming the component, the component comprising an outer surface;
forming a shim into the passive strain indicator, the passive strain indicator comprising the shim and a plurality of fiducial markers on the shim, the plurality of fiducial markers formed on the shim by deforming selected locations on the shim; and
attaching at least a portion of the shim to the outer surface of the component;
wherein forming the component and forming the passive strain indicator are performed separately prior to attaching at least a portion of the shim to the outer surface of the component, and, wherein the plurality of fiducial markers are arranged in a predetermined pattern; and
,wherein the predetermined pattern comprises an analysis region, a locator region, and a serial region, and wherein at least one of the plurality of fiducial markers is formed in each of the analysis region, the locator region, and the serial region.

Abstract
A method of making a component with a passive strain indicator includes forming the component including an outer surface thereof. The passive strain indicator includes a shim with a plurality of fiducial markers. The method also includes forming the plurality of fiducial markers on the shim by deforming selected locations on the shim. The method further includes attaching a portion of the shim to the outer surface of the component. Forming the component and forming the passive strain indicator are performed separately prior to attaching the shim to the outer surface of the component. A system for monitoring strain includes a component and a passive strain indicator. A portion of the passive strain indicator is integrally joined with the outer surface of the component. The passive strain indicator includes a shim and a plurality of fiducial markers. Each fiducial marker is a discrete three-dimensional feature on the shim.
