✦ Synopsis

Four types of integral ®nite elements have been developed and used to estimate the dynamical characteristics of elastic±viscoelastic composite structures, namely sandwich beam, plate and shell structures with viscoelastic materials as core layers. The results of the integral ®nite element prediction are compared with those from the direct frequency response method and experiment, showing that the numerical stability, convergence and accuracy of the integral ®nite elements are satisfactory in terms of engineering applications.
