Application of the dynamic stiffness technique to the in-plane vibrations of plate structures
(Pergamon-Elsevier Science Ltd, 1996)In this study the dynamic stiffness technique, which yields ''exact'' results for a certain class of plate structure, is extended to include in-plane vibrations. Using the equations of motion and edge tractions the stiffness ... -
An assessment of the effects of in-plane vibrations on the energy flow between coupled plates
(Academic Press Ltd, 1996)The majority of the studies of energy transmission in plate-type structures are based on the assumption that the main component of the energy transfer is due to flexural waves, and the contribution of in-plane waves may ... -
