Abstract
This project was conducted to validate the measurement of static strain and dynamic frequency in an aluminum beam using 3D photogrammetry technology against analytic modeling and conventional strain measurements. A review of the 3D photogrammetry literature was conducted and a summary is presented here. Static load displacement and strain were compared between analytical calculations, photogrammetric data, strain gauges, experimental measurements, and an FEA model. First mode forced vibration was validated between analytical work, FEA, accelerometers, and photogrammetric measures. Results yielded positive and repeatable correlations between photogrammetric data and analytical computations with most reliable results for displacement.
