Popis:	Problems related with the modeling and behavior in free vibration of doubly curved sandwich panels with laminated face sheets are developed in this paper. Implications of anisotropy and stacking sequence of face sheets as well as of transverse orthotropy of the core on the free vibration behavior are highlighted. Other parameters, mainly geometrical ones, are also considered in the numerical simulations, and their implications on the vibrational behavior are put into evidence. Because of the absence of similar results in the specialized literature, this paper is likely to fill a gap in the state of the art of this problem and provide pertinent results that are instrumental in the design of advanced sandwich shells.
