667 - Spectral element and experimental analysis of lightweight sandwich structures
Bonfiglio P., Peplow A., Nilsson A., Pompoli F.
Abstract
The dynamic response of the vibrating structures are studied with the standard finite element method against the more computationally efficient spectral finite element method. First a simple beam structure is modelled with the standard method and newly developed spectral elements; which has the advantage that dispersion relations for all beam structures may be developed. Some numerical examples are given to illustrate and validate the developed method and studies of the measured responses of structures that may be used for vehicle panels are compared.
