Abstract

Full field displacement and full-field dynamic stress-strain information has been shown to be estimated accurately from limited sets of data using an expansion algorithm through analytical simulations. Experimental data is collected and used for the dynamic expansion process to predict dynamic stress-strain for a candidate structure. Experimental measurements are obtained in a controlled study using an impact excitation technique. Displacement data at limited locations is collected using dynamic photogrammetry and digital image correlation techniques. The full-field expanded displacement data is compared and validated with a reference solution. This full-field displacement data is then used to identify the dynamic stress-strain to show the usefulness of the technique.
