The motivation for this report is a proposed new microelectromechanical systems (MEMS) sensor with applications in civil infrastructure sensing. This report analyzed the influence of three assumptions employed in the Euler-Bernoulli, Rayleigh, and Timoshenko beam theories by comparing their results to a three-dimensional, elasticity-based approximation for vibrational frequencies and mode shapes. The results of this report showed that all three theories are insufficient when a fixed support is involved, so the elasticity-based approximation was utilized to calculate the frequencies for the bridge component in the MEMS device. These results have been passed on to the developers so that the testing process could move forward in the hopes that the device could advance the field of structural health monitoring in the future.
