Abstract

The present paper deals with the analysis of displacement field forms effects on natural frequencies for flexure problems of laminated sandwich beams. Several forms using various parameters are tested. Both analytical and finite elements formulations using Hamilton’s principle are carried out. Numerical results have been computed of a sandwich beam and compared in order to highlight the importance of inclusion of such parameters and its capacity for good estimation of natural frequencies of sandwich beams.
