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
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.
Three-point bending tests are performed to find the flexural and shear rigidities of sandwich beams
