A Generalized Rayleigh-Ritz Method for Structural Dynamics Problems in Conjunction with Finite Elements.

reportActive / Technical Report | Accession Number: ADA126481 | Open PDF

Abstract:

A 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 strong discontinuities.
