6, a and 6, b shows the variation of the first natural frequency of the sandwich beam versus the thickness ratio, with various fiber orientations.
For both Models I and II, it can be indicated that the frequency of the sandwich beam with fiber orientation [theta] = 0[degrees] is relatively high compared with the others cases.

Strength and stiffness of
sandwich beams in bending.
Some specific areas investigated include nonlinear stress and deformation behavior of composite
sandwich beams, a neural network approach for locating multiple defects, first-order size effects in the mechanics of miniaturized components, and deformation evaluation of solder ball joints by electromotive force.
The Influence of Fatigue Cracks on the Modal Vibration Response of Composite
Sandwich BeamsThree-point bending tests are performed to find the flexural and shear rigidities of
sandwich beams [15].
