Rayleigh's method vibration examples
WebEquation ( 9.8) is known as Rayleigh’s Quotient. This result tells us that if a mode shape corresponding to a particular natural frequency is used in the ratio in ( 9.8 ), then the result … WebA solution formulation of generalized Rayleigh-Ritz method is described and applied to two initial and boundary value problems of stress waves and structural dynamics in conjunction with finite element discretization. Excellent numerical results have been obtained for wave equations associated with lateral and longitudinal vibrations and with ...
