The natural frequencies of the simply supported of a sandwich beam
are expressed analytically by [8, 11]:
Based on previous considerations, in this paper we determined a designed map for sandwich beam
with aluminium faces and cork core loaded in three-point bending such in figure 3.
8] used the finite element and harmonic balance methods to calculate the instability regions of the sandwich beam
with an electrorheological fluid core subjected to an axial dynamic force.
The flexural rigidity of an open sandwich beam
assumed to have thin skins of equal thickness represents the sum between the flexural rigidities of the skins and core determined about the centroidal axis of the whole cross section (Zenkert, 1997):

Investigation of dynamics of sandwich beam
is presented in .
