The prediction of the response of structures with complex geometries has seen extensive work analytically and numerically, with incomplete experimental work. In this investigation the non-contact full-field 3D digital image correlation (3D-DIC) technique coupled with high-speed imaging and the Fast Fourier Transform (FFT) are used to study the dynamic behavior of a clamped-clamped curved beam subjected to harmonic base excitation. Images were processed using 3D-DIC to gather the full-field displacement measurements of the beam. The effect of the clamping process on the radius of curvature of the beam was characterized prior to the swept-sine test. During testing, 1024×512-pixel images were taken at a rate of 3000 fps. Natural frequencies and mode shapes were determined for a curved beam subjected to a swept-sine test at an excitation of 9g's and over a frequency range of 60 - 430 Hz.
