Free Vibration Analysis of a Folded Plate by Transfer Influence Coefficient Method

This paper deals with the free vibrations of folded plates by the transfer influence coefficient method. The governing equations of a non-circular cylindrical shell including a plate as special case are written in a coupled set of first order matrix differential equations. The Runge-Kutta-Gill integration method is used to solve the governing differential equations. The natural frequencies and corresponding mode shapes are calculated numerically for the folded plate of various crank angles. All boundary conditions and the intermediate supports between folded plate and foundation could be treated only by adequately varying the values of the spring constants.
