Abstract: Methods for determining strain on turbine components include providing a turbine component comprising a plurality of strain sensor reference features disposed along the turbine component separated from one another by a plurality of first distances at a first time, reading the plurality of strain sensor reference features at a second time to determine a plurality of second distances between the plurality of strain sensor reference features, and comparing the plurality of second distances to the plurality of first distances to determine a plurality of non-linear strain measurements between the plurality of strain sensor reference features.

Abstract: Systems and methods for monitoring component deformation are provided. The component has an exterior surface. A method includes directly measuring a passive strain indicator configured on the exterior surface of the component along an X-axis, a Y-axis and a Z-axis to obtain X-axis data points, Y-axis data points, and Z-axis data points. The X-axis, Y-axis and Z-axis are mutually orthogonal. The method further includes assembling a three-dimensional profile of the passive strain indicator based on the X-axis data points, Y-axis data points and Z-axis data points.
