Uncertainty of Digital Image Correlation with Vibrating Deformable Targets,ile a laser triangulation sensor was used as a reference transducer in a section of the beam. Effect of exposure time, sensor gain and vibration amplitudes on measuring the uncertainty is explored. A software was developed to synchronize the laser and camera, while DIC analysis was done with Vic-2D

Modal Analyses and Experimental Verifications of Joined-Wing Configurations,cteristics of the joined-wing configurations. In numerical analyses, the natural frequencies and the corresponding mode shapes for the configurations are obtained by using ANSYS software. Then the results of selected configurations are verified via modal testing so as to achieve accurate finite elem

Modal Testing of James Webb Space Telescope (JWST) Optical Telescope Element (OTE),n fixture necessitated additional testing and analysis to validate the model boundary condition. The deployed configuration testing was successfully performed with 188 modes extracted up to 100 Hz. This paper provides details on the overall test effort and insight into the performance of a modal tes

Structural Design with Joints for Maximum Dissipation, structures, joints represent the main source of energy dissipation. In this work a minimal model is used to show how structural performance can be improved using joints as a design variable. Common optimization tools are applied to a nonlinear joint model in order to damp undesired structural vibra
