Estimation of fundamental frequency of non-circular plates with free, circular cutouts
A method of obtaining approximate fundamental frequencies of slightly non-circular plates with free circular cutouts is developed. An approximate expression for the radius of each bounding curve is written as a truncated Fourier series. The support conditions, which are written in terms of a perturb...
