Abstract Scope |
Strain measurement methods such as Strain Gauges and DIC (Digital Image Correlation) are restricted by the shape and location of the structure under evaluation and may require wiring through confined, inaccessible, exposed, and/or high-temperature environments. This paper presents a novel approach for measuring mechanical strain via additively manufactured fluid circuits that conform to the structure under evaluation. Structural deformation changes the volume inside the fluid circuits, varying the pressure. Static analysis will be performed to reveal the relationship between change in pressure and strain. To validate the static analysis, experiments will be conducted on metal structures with additively manufactured conformal fluid circuits. These results will serve as building blocks for a novel non-destructive strain evaluation method with applications such as long-term monitoring of safety-critical structures such as aircraft and bridges. |
