Natural Frequency Analysis Of A Box-type Structure Using Ritz Method With Polynomial Shape Functions
This research work is aimed at analyzing the vibration associated with a box-type structure using Ritz Method with polynomial shape function. The purpose is to determine the fundamental frequency. The study assumed the same boundary conditions used by Onwuka and Nwachukwu (2012) and formulated a handy expression, for determining the natural frequency of a box structure. The results of the
