Title: CTE Measurements for Loading Scenarios

The goals are to 1. understand full field thermal expansion of system parts by using strain gauges, DIC, and possibly ESPI. This is ultimately used to update a Finite Element Model relating to stockpile stewardship. 2. To verify the resolution of digital image correlation methods for thermal expansion measurements (CTE). A few conclusions: To this point, the DIC data shows more noise (less resolution) than we would like and Strain Gauge data is sound but it is more localized than full field.
